It has been~ hown~-~ that a-phenyl-and ala-diphenyl-y-dialkylaminobutyronitriles, when heated with concentrated hydrochloric or hydrobromic acid, were converted into salts of l- alkyl-2-imino-3-phenyl (or 3, 3-diphenyl) pyrrolidines or the corresponding 2-pyrrolidone. It was found7 that when ala-diphenyl-y-diethylaminobutyronitrile (I) 8 was heated at 270- 275'in a stream of hydrogen chloride, 1-ethyl-2-imino-3, 3-diphenylpyrrolidine ...
