Reaction Conditions

Reaction Steps

To a solution of (2,3-bis{[2-(methyloxy)ethyl]oxy}phenyl)methanol (1.12 g, 4.37 mmol) and triethylamine (0.49 g, 4.84 mmol) in dichloromethane (20 mL) was slowly added thionyl chloride (0.78 g, 6.58 mmol) at 0° C. The solution was stirred at 0° C. for 15 min, and then at rt for 3 h. Dichloromethane (80 mL) was added, the solution was washed with water (50 mL), sat. sodium bicarbonate (50 mL), and brine (50 mL), dried with sodium sulfate, and concentrated to give crude 1-(chloromethyl)-2,3-bis{[2-(methyloxy)-ethyl]oxy}benzene (1.15 g, 96% yield) as a yellow oil. 1H NMR (400 MHz, CDCl3) δ7.02 (m, 2H), 6.90 (dd, 1H), 4.72 (s, 2H), 4.27 (m, 2H), 4.14 (m, 2H), 3.77 (m, 2H), 3.73 (m, 2H), 3.46 (s, 3H), 3.44 (s, 3H).
