Procedure

The mixture of 3.55 g of N-(4-nitro-o-tolyl)-4-trifluoromethylphthalimide, 200 ml of 95% aqueous ethanol and 0.18 g of 5% palladium on carbon is hydrogenated at 3.1 atm. and 45° until the hydrogen uptake ceases. It is filtered, evaporated and the residue recrystallized from ethanol, to yield the N-(4-amino-o-tolyl)-4-trifluoromethylphthalimide melting at 161°-163°.
