Participants

Reaction Steps

To a mixture of N-benzyl-[2-(2-methylamino-3-nitro-phenoxy)-ethyl]-carbamic acid tert-butyl ester (520 mg, 1.30 mmol) and 10% palladium on carbon (120 mg ) in ethanol (40 mL) at 50° C. was added a solution of hydrazine hydrate (1.3 g) in ethanol (10 mL). The reaction was allowed to stir for 3 hr then the catalyst filtered through celite and the solvent removed. Purification by chromatography (30% ethyl acetate-hexane) afforded 380 mg (78.9%) of a clear oil; MS EI m/e 371 (M+); IR (film) 3400,3350,1680 cm-1.
