Reaction Steps

A solution of 29.0 g. of α,α-diphenyl-α-(1-isopropyl-3-pyrrolidinyl)acetonitrile in 100 ml. of conc. sulfuric acid was heated at 80° C. for 18 hours. The reaction mixture was poured onto ice, the resulting cold acidic solution made basic using sodium hydroxide and the basic solution extracted with chloroform. The dried chloroform extract was concentrated and the residue crystallized from isooctane. The solid was recrystallized from isopropyl ether to give 13.2 g. (43%) of product which melted at 110.5°-112.5° C.
