Reaction Steps

Thionyl chloride (2 mL) was added to solution of (4-benzyloxy-3-chloro-5-methoxy-phenyl)-methanol (CAB02170, 2.703 g, 9.7 mmol) in dichloromethane (10 mL). The solution was stirred for 1 h at room temperature, then diethyl ether (50 mL) and water (20 mL) were added. The organic layer was separated, washed with conc. sodium bicarbonate solution (10 mL), dried over sodium sulphate and concentrated under reduced pressure. The residue was dissolved in dichloromethane (5 mL) and precipitated by addition of hexane (ca. 50 mL). Yield: 2.730 g (95%) white powder. 1H-NMR (400 MHz, CDCl3) δ=3.89 (s, 3H, —OCH3), 4.52 (s, 2H), 5.07 (s, 2H), 6.87 (d, J=2.0 Hz, 1H), 7.03 (d, J=2.0 Hz, 1H), 7.33-7.43 (m, 3H), 7.53-7.58 (m, 2H). LRMS (FAB+): 91.0 (100), 296.0 (17, [M+H]+).
