실험 절차

To a suspension of 3-(6,6-dimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-3-yl)-propionic acid (1.65 g, 7 mmol) in dichloromethane (15 mL) was added 1.36 g (8.4 mmol) of carbonyldiimidazole. The mixture was stirred at room temperature until the solution became clear. To the mixture was added dimethylamine (14 mL of a 2.0M solution in tetrahydrofuran). The mixture was stirred at room temperature overnight and then concentrated. The residue was redissloved in dichloromethane, washed with brine and concentrated. The solid was washed with ethyl acetate until it became white and dried to give 1.4 g (78% yield) of 3-(6,6-dimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-3-yl)-N,N-dimethyl-propionamide. 1H-NMR (360 MHz, diemthylsulfoxide-d6) δ10.93 (br s, 1H, NH), 6.48 (s, 1H), 2.94 (s, 3H, CH3), 2.79 (s, 3H, CH3), 2.72 (m, 2H, CH2), 2.57 (s, 2H, CH2), 2.48 (m, 2H, CH2), 2.17 (s, 2H, CH2), 1.00 (m, 6H, 2×CH3). MS m/z 262 [M+].
