Methyl 2-(1-methyl-1H-indol-3-yl)acetate

58665-00-2

Methyl 2-(1H-indol-3-yl)acetate (200 mg, 1.1 mmol) was dissolved in N,N-dimethylformamide (3 mL). To this solution was added sodium hydride (60 mg, 60% dispersed in mineral oil, 1.5 mmol). Subsequently, iodomethane (223 mg, 1.58 mmol) was added and the reaction mixture was stirred at room temperature for 6 hours. The progress of the reaction was monitored by thin layer chromatography (TLC). Upon completion of the reaction, the reaction solution was acidified to pH 3-4 with 6N hydrochloric acid, diluted with the addition of water (5 mL), and then extracted with ethyl acetate (5 mL × 3). The organic layers were combined, washed twice with saturated saline and dried over anhydrous sodium sulfate. After concentration under reduced pressure to remove the solvent, the residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate = 5:1) to afford methyl 2-(1-methyl-1H-indol-3-yl)acetate (140 mg, 65% yield).1H NMR (400 MHz, CDCl3): δ 7.60 (d, J = 7.9 Hz, 1H), 7.29 (d, J = 8.2 Hz, 1H), 7.23 (dd, J = 8.2, 7.9 Hz, 1H), 7.12 (dd, J = 8.2, 7.9 Hz, 1H), 7.03 (s, 1H), 3.77 (s, 3H), 3.75 (s, 2H), 3.69 (s, 3H); 13C NMR (100 MHz, CDCl3): δ 172.6, 136.9, 127.7 136.9, 127.7, 121.7 (2C), 119.26, 118.9, 109.3, 106.8, 51.9, 32.7, 31.0.
