Reaction Steps

To an initial charge of 81.0 g of 2-pyrrolidone in 200 ml of toluene there are added, dropwise and with ice cooling, 54.7 g of chloroacetyl chloride such that the temperature of the reaction mixture remains at 5° C. Following the addition the reaction mixture is stirred at room temperature for 6 hours. The resulting precipitate is filtered off with suction and the solvent is removed in vacuo to give 74.5 g of N-(chloroacetyl)pyrrolidone, corresponding to a yield of 97%.
