Procedure

Fifty-three grams (0.17 mole) of 4,5-dihydro-3,3-diphenyl-4-isopropylaminomethylfuran-2-(3H)one was dissolved in 300 ml. of boiling isooctane and 0.25 g. of 67% sodium hydride added. After refluxing for 6.5 hours an additional 0.25 g. of 57% sodium hydride was added and refluxing was continued overnight. The cooled mixture was filtered and the solid was recrystallized from toluene. The 3,3-diphenyl-4-hydroxymethyl-1-isopropyl-2-pyrrolidinone weighed 42 g. (80%) and melted at 159°-161° C.
