HCID 32960211,1-Bis(4-pyrrolidinophenyl)ethyleneYield 50%

Procedure

In the same manner as in 1-2 of Example 1 except for using the thus obtained 1,1-bis(4-pyrrolidinylphenyl)ethane instead of 1,1-bis(4-dimethylaminophenyl)ethane and using hydrochloric acid instead of nitric acid in 1-2 of Example 1, 1,1-bis(4-pyrrolidinylphenyl)ethylene (m.p. 211° C.) was obtained in a yield of about 50%.
