실험 절차

A solution of pyrrolidine (35 grams; 0.5 mol) and triethylamine (50 grams; 0.5 mol) in benzene (500 ml) is placed in a glass reaction flask equipped with a mechanical stirrer and reflux condenser. β-Chloropropionyl chloride (64 grams; 0.5 mol) is then slowly added with stirring over a period of about 15 minutes. Stirring is continued for a period of about 30 minutes. After this time the reaction mixture is first filtered to remove triethylamine hydrochloride nd is the stripped of benzene to yield 1-(β-chloropropionyl) pyrrolidine.
