Reaction Conditions

Reaction Steps

To a solution of 1-[6-benzyloxy-2-hydroxy-3-(5-methyl-7-nitroindan-4-yloxy)phenyl]ethanone (1.50 g) in n-propanol (15 mL) was added ethyl carbazate (432 mg). The mixture was stirred under an argon atmosphere at 75° C. overnight and cooled to room temperature. Adding hexane (30 mL), the reaction mixture was stirred for 1 hour. The precipitate was filtrated to give ethyl N′-{1-[6-benzyloxy-2-hydroxy-3-(5-methyl-7-nitroindan-4-yloxy)phenyl]ethylidene}hydrazinecarboxate (1.16 g).
