Conditions

Temperature: 90 °C

Procedure

Methyl 3-(bromomethyl)benzoate (4.0 g) was mixed with toluene (40 ml), and triphenylphosphine (5.0 g) was added thereto, followed by stirring at 90° C. overnight. The precipitated solid was collected by filtration to obtain [3-(methoxycarbonyl)benzyl](triphenyl)phosphonium bromide (8.2 g).
