Reaction Steps

45 g. of the 3-methyl-4-p-nitrophenyl-2-pyrrolidinone prepared in Example 5 are dissolved in 3 liters of absolute ethanol and hydrogenated at 100°C. with hydrogen at a pressure of 90 kg./cm.2, in the presence of 5 g. of Raney nickel as catalyst. When the hydrogen absorption has finished, the catalyst is filtered off and the filtrate is evaporated to dryness. The residue is recrystallized twice from ethanol. 30 g. of 4-p-aminophenyl-3-methyl-2-pyrrolidinone are obtained. M.P. : 190°-194°C.
