Procedure

Refer to Chart D. 3-Carboxypropyltriphenylphosphonium bromide is prepared by heating triphenylphosphine (156.8 g.) and 4-bromobutyric acid (100 g.) in 125 ml. of benzene at reflux for 18 hrs. The crystalline product is filtered off, washed with benzene, and recrystallized from ethanol-acetonitrile-ether, 150 g., m.p. 247°-249° C.
