45.5 ml of a solution of 4N-hydrogen chloride/ethyl acetate was added to 10 g of 2-(tert-butoxycarbonylamino)-N-(4-cyanophenyl)acetamide in a closed vessel and stirred for 18 hours. The crystals formed were removed by filtration, washed with ethyl acetate and then dried under a reduced pressure to obtain 7.7 g of 2-amino-N-(4-cyanophenyl)acetamide hydrochloride. 58.8 ml of an 5 aqueous saturated solution of sodium hydrogencarbonate and 20 ml of water were added to 3.7 g of the hydrochloride and stirred for 1 hour. The crystals thus formed were taken out by filtration and dried under a reduced pressure to obtain 2.5 g of 2-amino-N-(4-cyanophenyl)acetamide.
