Procedure

Into 50 ml of 5% aqueous solution of sodium hydroxide was dissolved 5 g of 2-(4-methoxyphenyl)-2-(4-pyrrolidinophenyl)propionic acid. Thereto was gradually added dropwise 2.4 g of 35% aqeous solution of hydrogen peroxide and the mixture was reacted at room temperature with stirring for 2 hours, and further at 60° C. with stirring for one hour. The reaction mixture was cooled and the precipitated crystal was collected by filtration. The crystal was recrystallized from methanol to give 3.0 g (yield 69.9%) of 1-(4-methoxyphenyl)-1-(4-pyrrolidinophenyl)ethylene, having a melting point of 159°~162° C.
