Reaction Steps
To 60 ml. of concentrated sulfuric acid preheated to 60° C. was added 21.7 g. (0.082 mole) of α,α-diphenyl-α-(1-methyl-3-azetidinyl)acetonitrile at a rate so as to maintain a temperature of 60°-70° C. The solution obtained was heated to 70° C. for 18 hrs. and extracted with chloroform. The chloroform extract was dried over sodium sulfate and concentrated and the residue crystallized from ethyl acetate-isopropyl alcohol to give 13.8 g. of the free base (60%) melting at 171°-174° C. The base was treated with hydrogen chloride in isobutyl methyl ketone and the salt recrystallized from isopropyl alcohol to give 9 g. of product melting at 182°-185° C.
