Reaction Steps

A solution of 3-(4-bromo-phenyl)-propane-1,2-diol (1.41 g, 6.10 mmol) and p-toluenesulfonic acid (50 mg) in DMF (10 mL), 2,2-dimethoxypropane (10 mL) is stirred at rt for 2 h. The reaction mixture is diluted with sat. aq. NaHCO3 (150 mL) and extracted with diethyl ether (2×200 mL). The organic extracts are washed with water (200 mL), dried over MgSO4 and evaporated to give 4-(4-bromo-benzyl)-2,2-dimethyl-[1,3]dioxolane (1.57 g) as a pale brownish oil; LC-MS: tR=1.00 min.
