Murray and Cloke5 synthesized four (methyl-, ethyl-, n-propyl-and n-butyl-) Z-pheny1-3-alkyl- 3-phenyl-A'-pyrrolines from 4-chloro-2-alkyl-2-phenylbutyronitriles and phenylmagnesium bromide. As a rule, they refluxed the Grignard reagent and the nitrile for eight hours in ether, and added the cooled mixture to liquid ammonia. After evaporation of the ammonia, the 4l- pyrrolines were isolated from the residue. Yields were: CH3, 78%; CzH5, 70%; n-C3H7, ...
