반응 단계
A mixture of 2-chloroethyl 4-methylbenzenesulfonate (39; 27.0 g, 0.115 mol), 2-hydroxybenzaldehyde (25; 14.0 g, 0.115 mol) and K2CO3 (31.7 g, 0.23 mol) in DMF (100 mL) was stirred at 45° C. for 12 h. Water (200 mL) was added and the mixture was extracted with ethyl acetate (3×150 mL). The combined organic layers were washed saturated brine (3×50 mL), dried (Na2SO4) and concentrated under reduced pressure. The resulting residue was purified by chromatography (petroleum ether:ethyl acetate=10:1) to give 2-(2-chloroethoxy)benzaldehyde 40 (16.8 g, 0.091 mol, 79%) as a pale yellow solid.
