실험 절차

Thionyl chloride (13.1 g, 0.11 mol) was added slowly to a stirred solution of 2,3-dimethylbenzofuran (18.0 g, 0.10 mol) and pyridine (8.3 cm3, 0.105 mol) in dichloromethane (170 cm3) at below 5° C., and the solution was heated under reflux for 3 hr. The solution was poured into water and separated, the organic layer was washed with water, dried (Na2SO4), filtered and the solvent was removed to give 6-chloromethyl-2,3-dimethylbenzofuran (16.2 g, 0.078 mol, 76.4%). (Found: C, 67.76; H, 5.65; Cl, 18.21. C11H11ClO requires C, 67.87; H, 5.70; Cl, 18.22%) m.p. 63°-65° C. [ex petroleum ether (b.p. 60°-80° C.)].
