Reaction Conditions

Reaction Steps

A flask is charged with 5-hydroxymethyl-2-methylsulfonyl-benzonitrile (0.788 g, 3.73 mmol) in toluene (5 mL) and heated at 40° C. PBr3 (0.175 mL, 1.86 mmol) is added and the reaction is refluxed for 0.5 h. It is then cooled to room temperature, diluted with dichloromethane and washed with water. The aqueous layer is extracted with dichloromethane. The combined organic layer is dried over sodium sulfate and concentrated in vacuo to afford 5-bromomethyl-2-methanesulfonyl-benzonitrile as a white solid. 1H NMR (400 MHz, CDCl3) δ ppm 3.28 (s, 3H), 4.89 (s, 2H), 7.80 (d, J=8.3 Hz, 1H), 7.94 (s, 1H), 8.18 (d, J=8.1 Hz, 1H).
