2.50 g of ethyl (R/S)-2-(3-hydroxy-2-oxo-1-pyrrolidinyl)acetate are treated with 11.5 ml of approximately 25% ammonium hydroxide solution, whereupon the mixture is stirred at room temperature for 1 hour. The mixture is treated with acetonitrile and evaporated. The residue is treated five times with acetonitrile and in each case again evaporated. There is obtained (R/S)-2-(3-hydroxy-2-oxo-1-pyrrolidinyl)acetamide which melts at 163°-164° after recrystallization from methanol/diethyl ether (1:2).
