Hydrochloric Acid → 2-amino-N-(4-cyanophenyl)acetamide hydrochloride

Participants

Reaction Steps

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