Reaction Conditions

Reaction Steps

To a solution of 9-bromo-nonanoic acid (7.00 g, 29.5 mmol) in toluene (10 mL) was added triphenylphosphine (7.74 g, 29.5 mmol). The solution was sealed under nitrogen in a pressure tube and heated at 110° C. for 18 hours. On reaction completion two phases were observed. The toluene top layer was decanted from the crude product which was washed with toluene. (8-Carboxy-octyl)-triphenyl-phosphonium bromide (14.9 g) was obtained, which was directly used in the next step. White semisolid, m/e=419.3 ([M+H]+).
