Phosphorus tribromide → (4-Bromomethyl-2-methyl-benzyloxy)-tert-butyl-diphenyl-silane

Participants

Reaction Steps

To a stirred solution of [4-[(tert-butyl(diphenyl)silyl)oxymethyl]-3-methyl-phenyl]methanol (0.3 g, 0.76 mmol) in DCM (30 mL) is added phosphorus tribromide (0.072 mL, 0.76 mmol) at 0° C. and the reaction mixture is stirred for 1 hour. The reaction mixture is diluted with dichloromethane (50 mL), washed with aqueous sodium bicarbonate solution, dried over magnesium sulphate, and concentrated under vacuum to give the title compound as a light yellow liquid (0.3 g, crude). ESI/MS m/z 438.1 (M+H)+.
