Hydrazine hydrate (1:1) → 2-Amino-6-(2-phenoxyethoxy)benzamide

Participants

Reaction Steps

The crystallized 2-nitro-6-(2-phenoxyethoxy)benzonitrile (5.82 g, 0.0205 mole) is stirred in 116 ml absolute ethanol at 50°C. and 3.62 ml (0.0615 mole) 85 percent hydrazine hydrate is added, followed by small scoops of Raney nickel. The temperature is kept at 50°-60°C. while the Raney nickel is added, and after gas evolution and the exotherm ceases, the mixture is filtered through diatomaceous earth. The filter cake is washed with hot ethanol and the filtrate is concentrated, giving 2.804 g of 2-amino-6-(2-phenoxyethoxy)benzamide m.p. 127°-150°C.
