Procedure

A mixture of 3-(bromoethyl)benzoic acid, ethyl ester (12.2 g, 0.050 mol) and triphenyl phosphine (13.1 g, 0.05 mol) in toluene (50 ml) was stirred at 70° C. for 16 hours to yield [[3-(ethoxycarbonyl)phenyl]methyl]triphenylphosphonium bromide as a colorless crystalline solid which was filtered off, washed with toluene and dried under vacuum.
