実験手順: Ethyl α-Bromo-4-chloro-o-toluate (26.4 g.) is added to a solution (10°) of sodium methoxide (5.4 g.) in 110 ml. of methanol. When the addition is complete, the mixture is refluxed for two hours, then cooled and concentrated in vacuo. The oily residue is partioned between ether-water. The ether layer is separated and dried. Removal of the drying agent and concentration of the filtrate in vacuo leaves 17.3 g. of a white solid. A sample of the product recrystallized from methanol had mp 44°-45°. When the addition the mixture is refluxed for two hours cooled concentrated in vacuo The ether layer is separated dried Removal of the drying agent and concentration of the filtrate in vacuo leaves 17.3 g A sample of the product recrystallized from methanol

実験手順: A mixture of ethyl 2-(bromomethyl)-5-chlorobenzoate (0.553 g, 1.99 mmol), 4-isopropylaniline (0.269 g, 1.99 mmol) and sodium ethoxide (0.406 g, 5.97 mmol) in ethanol (40 mL) was heated at reflux overnight. After this time, the mixture was cooled to room temperature and concentrated under vacuum. The mixture was partitioned between 1 N HCl and ethyl acetate. The organic layer was separated, washed with 1 N HCl, then with 1:1 water/brine solution, dried over sodium sulfate and filtered. Concentration under vacuum and recrystallization from ethyl acetate afforded 6-chloro-2-(4-isopropylphenyl)isoindolin-1-one (0.302 g, 53%) as an off-white solid: m.p. 206-209° C.; 1H NMR (500 MHz, CDCl3) δ 7.89 (d, J=1.9 Hz, 1H), 7.73 (dt, J=8.6, 2.7 Hz, 2H), 7.55 (dd, J=8.1, 1.9 Hz, 1H), 7.45 (d, J=8.0 Hz, 1H), 7.30 (dt, J=8.5, 2.5 Hz, 2H), 4.83 (s, 2H), 2.96-2.90 (m, 1H), 1.26 (d, 6H); ESI MS m/z 286 [M+H]+. was heated at reflux overnight concentrated under vacuum The mixture was partitioned between 1 N HCl and ethyl acetate The organic layer was separated washed with 1 N HCl with 1:1 water/brine solution, dried over sodium sulfate filtered Concentration under vacuum and recrystallization from ethyl acetate
