remote from the nitro-group was attacked, yielding 2-methyl-3-nitrobenzylidene diacetate. The adjacent methyl group reacted with diethyl oxalate under the conditions of the Claisen condensation; oxidation of the product gave 2-methyl-6-nitrophenyl-acetic acid which, on reductive cyclisation, gave 4-methyloxindole.
