title: Methyl 1-[(Z)-2-(benzyloxycarbonyl)hydrazin-1-ylidene]-5-chloro-2-hydroxy-indane-2-carboxylate.
abstract: The title compound, C19H17ClN2O5, is an important inter-mediate for the synthesis of the pesticide Indoxacarb [systematic name: (S)-methyl 7-chloro-2-{[(meth-oxy-carbon-yl)[4-(tri-fluoro-meth-oxy)phen-yl]amino]-carbon-yl}-2H,3H,4aH,5H-indeno-[1,2-e][1,3,4]oxadiazine-4a-carboxyl-ate] The C=N double bond has a Z conformation. An intra-molecular 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 R (4) 4(12) motifs.
