Reaction Steps
4.5 g (1.6 ml, 16.7 mmol) Phosphorus tribromide were added portion-wise, with stirring to a solution of 4.98 g (33.0 mmol) rac-1-p-tolyl-propan-1-ol and 0.37 ml pyridine in 17 ml anhydrous diethyl ether at 0° C. The reaction mixture was warmed to ambient temperature and the reaction monitored by HPLC to completion. The reaction mixture was poured onto ice-water and the whole was extracted with dichloromethane. The organic phase was washed with brine, dried over MgSO4 and evaporated to give rac-1-(1-bromo-propyl)-4-methyl-benzene as a colourless oil that did not require further purification: NMR (CDCl3, ppm): 1.01 (3H, t), 2.28 (2H, m), 2.40 (3H, s), 4.92 (1H, t), 7.20 (4H, m).
