The reaction mixture was cooled and evaporated under reduced pressure to give an oily residue. This residue was dissolved in dichloromethane, washed with 2N sodium hydroxide (2×), washed with brine (2×), dried (MgSO4), and evaporated under reduced pressure to give an oil. This was triturated under petroleum ether (40°-60°) (200 ml) with cooling to afford 2-(4-benzyloxy-3-methylphenyl)ethanol as a white solid (26.0 g).
