Procedure

Fifty milligrams of 10% palladium on carbon were added to a mixed solution of 261 mg of 3-[N-(2-chlorobenzyl)amino]-4-nitrobenznitrile, 15 ml of methanol and 3 ml of 1,4-dioxane to conduct the catalytic reduction in a hydrogen atmosphere at 3 atm. After the completion of the reaction, the reaction solution was filtered through celite, and the filtrate was distilled off under reduced pressure. The resulting solid material was washed with ether, and was collected through filtration to give 196 mg of 4-amino-3-[N-(2-chlorobenzyl)amino]benznitrile.
