In the title compound, C31H29ClN2O3, the two heterocyclic rings, belonging to a system of five condensed rings, adopt conformations intermediate between twist-boat and sofa. The secondary amide group is involved in a weak intramolecular N—H⋯N hydrogen bond. In the crystal, molecules are linked by pairs of C—H⋯Cl hydrogen bonds to form inversion dimers. These dimers are linked via a C—H⋯O interaction to form chains propagating along the b-axis direction.

A solution of 2-amino-4-chlorophenol (3.0 mmol) and 2-bromobenzaldehyde (3.0 mmol) in MeOH (5 ml) was stirred at room temperature for 15 min. To the resultant mixture was added (E)-crotonic acid (3.0 mmol) followed by stirring for 5 min at the same temperature. Cyclohexyl isocyanide (3.0 mmol) was then added to the above mixture followed by stirring at 323 K for 48 h. The white precipitate of the U-4CR product was collected by filtration and the solid was washed with methanol (3 ml). The combined filtrate was concentrated under reduced pressure and the residue was purified by flash
over silica gel [eluting with 25% EtOAc in PE (b.p. 333–363 K)] to give additional portion of the U-4CR product. The yield of the U-4CR is 70%. A solution of the above U-4CR product (2.0 mmol), 2-bromobenzyl bromide (2.4 mmol), and K2CO3 (3.0 mmol) in acetone (reagent grade, 10 ml) was heated at 323 K for 2 h. The reaction was allowed to cool to room temperature. After adding water, the mixture was extracted using EtOAc (3 x 10 ml). The combined organic layer was dried over anhydrous Na2SO4, filtered off, and then evaporated under reduced pressure. The residue was purified by flash over silica gel [eluting with 20% EtOAc in PE (b.p. 333–363 K)] to give the O-benzylation product (96%).A 10-ml pressurized process vial was charged with the above O-benzylation product (0.15 mmol), Pd(OAc)2 (7.5 x 10-3 mmol; 5 mol %), K2CO3 (0.3 mmol), and PCy3HBF4 (1.5 x 10-2 mmol, 10 mol %). The vial was sealed with a cap containing a silicon septum. The vial was evacuated and backfilled with N2 (repeated for three times) through the cap using a needle. To the degassed vial was added degassed anhydrous MeCN (3 ml) through the cap using a syringe. The loaded vial was then placed into the microwave reactor cavity and was heated at 433 K for 80 min. After cooling to room temperature the reaction mixture was concentrated under reduced pressure and the residue was purified by flash
over silica gel [eluting with 25% EtOAc in PE (b.p. 333–363 K)] to give the title compound as a yellow solid (49 mg, 63%; m.p. 459–461 K (EtOAc-hexane). Single crystals suitable for X-ray diffraction were grown from a EtOAc/hexane mixture.The H atoms were placed in calculated positions with C—H = 0.93–0.98 Å, N-H = 0.86 Å and included in the
as riding on their carrier atoms with Uiso(H) =1.2Ueq (C,N).Data collection: PROCESS-AUTO (Rigaku, 2006); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound, C31H29ClN2O3, is a derivative of 7,8- dihydro-5H-6-oxa-7-azapicene, which was obtained from U-4CR of 2-amino-4-chlorophenol, 2-bromobenzaldehyde, (E)- crotonic acid and cyclohexyl isocyanide (Xing et al., 2006; Dai et al., 2008) followed by O-benzylation and palladium catalyzed intramolecular arylation (Wu et al., 2007). The structure of the title compound has been characterized by spectroscopic methods with further confirmation by X-ray analysis. We report here its crystal structure.
In the molecule of the title compound (Fig. 1), there are three benzene rings and the middle one was fused with two other benzene rings by CH2O and CH2N bridges closing six-membered heterocyclic rings. The middle benzene ring is twisted relative to two other benzene rings by 30.7 (3)° and 15.7( 3)°. In the crystal structure, the molecules are linked by two C—H···Cl weak hydrogen bonds into centrosymmetric dimers (Fig. 2).
