To a solution of (3,4-bis{[2-(methyloxy)ethyl]oxy}phenyl)methanol (0.82 g, 3.2 mmol) and pyridine (0.41 mL 5.1 mmol) in tetrahydrofuran (20 mL) at 0° C. was added thionyl chloride (0.26 mL, 3.5 mmol) and the reaction mixture warmed to room temperature and stirred for one hour. Then it was poured into water (40 mL) and extracted with ethyl acetate (3×40 mL). The combined extract was washed with water and brine (40 mL each), dried over sodium sulfate, filtered and concentrated to give 4-(chloromethyl)-1,2-bis{[2-(methyloxy)ethyl]oxy}benzene (0.65 g, 2.4 mmol, 75% yield) 1H NMR (400 MHz, CDCl3): 6.95-6.84 (m, 3H), 4.53 (s, 2H), 4.17-4.13 (m, 4H), 3.78-3.74 (m, 4H), 3.44 (s, 6H).
