Reaction Steps
Into 100 ml of 5% aqueous solution of sodium hydroxide was dissolved 10 g of 2,2-bis(4-pyrrolidinophenyl)propionic acid. Thereto was added 9.2 g of potassium persulfate and the mixture was reacted with stirring for one hour. The resulting precipitates were collected by filtration and recrystallized from methanol to obtain 7.0 g (yield 80%) of 1,1-bis(4-pyrrolidinophenyl)ethylene, having a melting point of 221°~223° C.
