A mixture of 100 g (599 mmol, Aldrich) of 4-bromobutyric acid and 157 g (599 mmol, Aldrich) of triphenylphosphine was heated to 130° for 2 hours. The reaction was cooled to room temperature. The resulting solid was solubilized in 250 mL of hot chloroform then diluted with 200 mL of diethyl ether. The mixture was cooled to room temperature then 0°. The solid which formed was collected by filtration and then dried under vacuum to afford 240 g (559 mmol, 93%) of title compound.
