Procedure

To a stirred mixture of (R)-methyl 6-fluoro-2-(2-methylpyrrolidin-2-yl)-1H-indole-4-carboxylate (1.0, 1.27 mol), CH3CN (50 ml) and methylbromoacetate (0.58 g, 3.82 mmol) was added DIPEA (0.82 g, 6.35 mmol). The reaction mixture was stirred at room temperature for about 20 hours. The reaction mixture was then diluted with CH2Cl2 (15 ml) and washed with water three times. The organic layer was dried with MgSO4 and concentrated to give 0.85 g of (R)-methyl 6-fluoro-2-(1-(2-methoxy-2-oxoethyl)-2-methylpyrrolidin-2-yl)-1H-indole-4-carboxylate. 1H NMR (CD3OD-d4) δ 7.47 (dd, 1H, J=2.4, 12.0 Hz), 7.27 (dd, 1H, J=2.4, 9.0 Hz), 6.89 (s, 1H), 3.95 (s, 3H), 3.66-3.68 (m, 1H), 3.64 (s, 3H), 3.16-3.17 (m, 2H), 2.72-2.75 (m, 1H), 1.88-2.02 (m, 4H), and 1.44 (s, 3H). MS (ESI) m/e [M+1]+ 349.0.
