실험 절차

A solution of methyl 4-bromomethyl-2-trifluoromethylsulfonyloxybenzoate (23.12 g; 61 mmol) and triphenylphosphine (16 g; 61 mmol) in toluene (240 ml) was refluxed for 5 hours. The resulting solid was filtered and washed with ether to give 3-trifluoromethylsulfonyloxy-4-methoxycarbonylbenzyl triphenylphosphonium bromide. Yield=100%.
