(Received 18 December 2011; accepted 18 December 2011; online 23 December 2011)

In the title compound, C15H17N3O3, the dihedral angle between the pyrimidine and benzene rings is 87.0 (7)°. In the crystal, mol­ecules are linked into inversion dimers with R22(8) graph-set motifs by a pair of N—H⋯O hydrogen bonds. Weak C—H⋯O hydrogen bonds and inter­molecular ππ inter­actions [centroid–centroid distance = 3.544 (1) Å] are also observed.

Comment top

The pyrimidine ring is found in vitamins like thiamine, riboflavin and folic acid (Cox, 1968). Barbitone, the first barbiturate hypnotic sedative and anticonvulsant, is a pyrimidine derivative (Russell, 1945). N-Substituted 2-arylacetamides are very interesting compounds because of their structural similarity to the lateral chain of natural benzylpenicillin (Mijin et al., 2006, 2008). Amides are also used as ligands due to their excellent coordination abilities (Wu et al., 2008, 2010).

Crystal structures of some acetamidederivatives, viz., 2-[(5,7-dibromoquinolin-8-yl)oxy]-N-(2-methoxyphenyl)acetamide (Wen et al., 2010), N-(4-bromophenyl)-2-(2-thienyl)acetamide (Nogueira et al., 2010), N-[4-(benzylsulfamoyl)phenyl]acetamide (John et al., 2010), 2-(4-fluorophenyl)-N-{4-[6-(4-fluorophenyl)-2,3-dihydroimidazo [2,1-b][1,3]thiazol-5-yl]pyridin-2-yl}acetamide (Selig et al., 2010) and recently from our laboratories, N-(3-chloro-4-fluorophenyl)-2-(naphthalen-1-yl)acetamide (Praveen et al., 2011) have been reported. As part of our ongoing studies of amides, the title compound is synthesized and its crystal structure is reported.

In the crystal structure of the title compound, C15H17N3O3, the dihedral angle between the pyrimidine and benzene rings is 93.0 (7)° (Fig. 1). Bond lengths are in normal ranges (Allen et al., 1987). Crystal packing is stabilized by N—H···O hydrogen bonds forming an R22(8) graph-set motif (Fig. 2). Weak C—H···O (Table 1) and ππ intermolecular interactions [centroid-centroid distance = 3.544 (1) Å] are also observed.

Experimental top

To a stirred solution of (3-methylphenyl)acetic acid (1 g, 6.65 mmol), triethylamine (1.34 g, 13.31 mmol) and 4,6-dimethoxypyrimidin-2-amine (1.02 g, 6.65 mmol) in dichloromethane (10 ml), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide HCl (1.52 g, 7.93 mmol) was added at 273 K. Reaction mixture was stirred at room temperature for 3 h. After the completion of the reaction, the reaction mixture was poured to ice cold water and the layers were separated. Organic layer was washed with 10% aq.NaHCO3 solution (10 ml), brine (10 ml), dried over anhydrous Na2SO4, filtered and concentrated under vacuum to obtain the crude product which was triturated with ethanol and filtered to afford 1.62 g of the title compound (I) as a white solid in 84% yield. Single crystals were grown from ethanol by the slow evaporation method (m.p. 381-382 K).

Refinement top

Atom H3N was located in a difference Fourier map and refined isotropically. All of the remaining H atoms were placed in their calculated positions and then refined using the riding model with C—H = 0.93 Å (CH), 0.97 Å (CH2) or 0.96 Å (CH3). The Uiso(H) values were set to 1.2 (CH, CH2) or 1.5 CH3) times Ueq of the parent atom.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
