Procedure

0.40 g of ethyl (R/S)-2-(3-acetoxy-2-oxo-1-pyrrolidinyl)acetate is treated with 45 ml of a saturated solution of ammonia in methanol. The mixture is left to stand at room temperature for 1 hour and then evaporated. The residue is treated four 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 (1:3).
