Procedure

An ice water chilled solution of 5-methoxycarbonyl-1-(2-propynyl)-2-pyrrolidinone (5.1 g) and sieve dried methanol (250 ml) was treated with anhydrous ammonia for ten minutes and was then allowed to stand overnight at ambient temperature. The solution was concentrated to afford an oil which crystallized (4.81 g). Recrystallization from 95% ethanol (20 ml) gave 3.07 g of almost colorless crystals, mp 145°-147° C.
