Procedure

A mixture of 1-(3,4-bis(benzyloxy)-5-nitrophenyl)-2-(2-(trifluoromethyl)pyridin-3-yl)ethanone (0.485 g, 0.93 mmol), ethyl carbazate (0.11 g, 1.06 mmol) and p-toluene sulfonic acid (4 mg) in toluene (10 mL) was refluxed until distillation of water ceased. The reaction mixture was cooled to room temperature, the solvents were evaporated to dryness, and the crude solid was triturated with diethyl ether (15 mL), filtered and dried yielding (Z)-ethyl 2-(1-(3,4-bis(benzyloxy)-5-nitrophenyl)-2-(2-(trifluoromethyl)pyridin-3-yl)ethylidene)hydrazinecarboxylate, 0.475 g (84%).
