실험 절차

Under nitrogen, aluminum chloride (0.7 g, 4.9 mmol) is slurried in dichloromethane (15 mL) then 4-chloro-3-sulfamoyl-benzoyl chloride (287 mg, 1.13 mmol) is added and allowed to stir at ambient temperature for 30 minutes. Then 1-ethyl-1,3,4,9-tetrahydro-indeno[2,1-b]pyridin-2-one (240 mg, 1.13 mmol) is added in 4 mL dichloromethane. The reaction is allowed to stir at ambient temperature for 1.5 hours. The reaction mixture is poured over ice-water and extracted with dichloromethane, the organic layer is separated and concentrated to give crude title compound as a brown oil. Recrystallization from warm dichloromethane afforded the title compound as a yellow powder (125 mg, 26% yield). 1H NMR (MeOD) δ 1.26 (t, 2H, J=7.01 Hz), 2.76-2.83 (m, 4H), 3.6 (s, 2H), 3.77 (q, 2H, J=7.01), 5.19 (s, 2H), 7.19 (d, 1H, J=8.11 Hz), 7.68-7.73 (m, 2H), 7.86 (d, 1H, J=1.09), 7.94 (dd, 1H, J=2.19, 8.11 Hz), 8.46 (d, 1H, J=1.97 Hz). MS (m/z): 431 (M+1).
