Procedure

The solution of 1.0 g of N-(4-nitro-o-tolyl)-4-methoxyphthalimide in 70 ml of ethyl acetate is hydrogenated over 0.35 g of platinum oxide at 2.5 atm. and room temperature for 2 hours. It is filtered, the filtrate concentrated and the precipitate formed collected, to yield the N-(4-amino-o-tolyl)-4-methoxyphthalimide melting at 158°-161°.
