Reaction Steps

A solution of 10.0 g (54.8 mmol) 2-chloro-5-nitrobenzonitril in 500 ml ethanol was hydrogenated at 40 psi by using 0.5 g 5% Pd-C as a catalyst. The catalyst was filtered off and the filtrate was evaporated in vacuo. Recrystallization (ethanol-water) gave 3.6 g (43%) 5-amino-2-chlorobenzonitril. M.p. 129-130° C.
