Reaction Steps
Two hundred and eighty eight milligrams of dihydro 1H-pyrrolizine-3,5(2H, 6H) dione is dissolved in 600 mg of m-chlorobenzyl alcohol and 0.2 ml of concentrated hydrochloric acid is added. The solution is heated at 100° C. for 40 hours. The mixture is cooled and is dissolved in 50 ml of anhydrous diethylether. The filtrate is cooled to induce crystallization and the resulting crystals are isolated by filtration. Recrystallization from toluene-petroleum ether yields 5-oxo-2-pyrrolidinepropanoic acid m-chlorobenzyl ester with a melting point of 90°-91° C.
