The title compound, C19H17ClN2O5, is an important inter­mediate for the synthesis of the pesticide Indoxacarb [systematic name: (S)-methyl 7-chloro-2-{[(meth­oxy­carbon­yl)[4-(tri­fluoro­meth­oxy)phen­yl]amino]­carbon­yl}-2H,3H,4aH,5H-indeno­[1,2-e][1,3,4]oxadiazine-4a-carboxyl­ate] The C=N double bond has a Z conformation. An intra­molecular N—H...O hydrogen bond occurs. In the crystal structure, O—H...O hydrogen bonds result in the formation of 12-membered rings lying about inversion centers with R44(12) motifs.

Comment top

The title compound, which was readily synthesized from the condensation of methyl 5-chloro-1,3-dihydro-2-hydroxy-1-oxo-2H-inden-2-carboxylate and phenylmethyl hydrazinecarboxylate, acts as an intermediate for the synthesis of Indoxacarb. In this article, the crystal structure of the title compound is presented (Fig. 1). The C=N double bond has a Z configuration. The N2—N1—C9—C8 torsion angle is 4.33 (3)°. The crystal structure is stabilized by intermolecular O1—H1···O2 and intramolecular N2—H2A···O1 hydrogen bonds, resulting in the formation of twelve-membered ring lying about an inversion center and representing R44(12) motif. In the crystal, there are weak intermolecular Cl···Cl interactions, with a distance of 3.379 (2) Å. The hydroxyl O atom lies 0.584 (2) Å from the mean plane of the phenyl ring C1···C6. The benzyl C atom lies 0.129 (2) Å from the mean plane of the phenyl ring C12···C17. The dihedral angle of the planes of two phenyl rings is 73.33 (3)°.

Experimental top

In a reaction flask, methyl 5-chloro-1,3-dihydro-2-hydroxy-1-oxo-2H-inden-2- carboxylate (11.20 g, 0.05 mol), phenylmethyl hydrazinecarboxylate (9.13 g, 0.055 mol) and p-toluenesulfonic acid monohydrate (0.95 g, 0.005 mol) were added to toluene (55 ml). The mixture was stirred at 66°C for 8 h. After completion of the reaction (monitored by HPLC), the mixture was cooled to room temperature and filtered. The filter cake was washed with cold methanol (20 ml) and dried at 40°C under vacuum for 4 h, giving a white solid. Single crystals were obtained by slow evaporation of a methanol and dichloromethane solution.

Refinement top

H atoms attached to C and O atoms were placed in calculated positions with O—H = 0.82 Å, C—H = 0.97 (methylene), 0.96 (methyl), 0.93 Å (aromatic H atoms), and Uiso(H) = 1.2Ueq (C, O) in the riding model approximation. The H atom attached to N was located in a difference Fourier map and refined with a distance restraint of N—H = 0.86 (1) Å and Uiso(H) = 1.5Ueq (N).

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.
