실험 절차

At ambient temperature, to a stirred mixture containing 2-bromo-4-(2-chlorobenzoyl)-6-ethylanisole (10.0 g, 28.2 mmol) and potassium t-butoxide (31.7 g, 0.283 mol) in ethylene glycol dimethyl ether (157 mL) was added H2O (1.52 mL). After 6 h, the reaction solids were collected by filtration and washed with ether (2×). The crude product was dissolved in H2O (200 mL), acidified with 2N HCl (pH <2) and stirred for 7 h. The precipitate was collected by filtration, washed with H2O (2×) and dried to give 5.37 g (73%) of the title compound. 1H NMR: consistent. mass spectrum (EI) m/z 258 (M+).
