Methyl bromoacetate → HCID 89657509, compound

Participants

Reaction Steps

(R)-Methyl 2-(2-methylpyrrolidin-2-yl)-1H-indole-4-carboxylate (190 mg, 0.74 mmol) was dissolved in CH3CN (25 ml) and methylbromoacetate (250 mg, 1.6 mmol). DIPEA (350 mg, 2.7 mmol) was then added. 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 146 mg of (R)-methyl 2-(1-(2-methoxy-2-oxoethyl)-2-methylpyrrolidin-2-yl)-1H-indole-4-carboxylate. 1H NMR (CDCl3-d) δ 7.85 (d, 1H, J=7.8 Hz), 7.13-7.29 (m, 3H), 4.92 (s, 2H), 3.95 (s, 3H), 3.70 (s, 3H), 3.56-3.62 (m, 2H), 1.95-2.06 (m, 4H), and 1.94 (s, 3H). MS (ESI) m/e [M+1]+ 331.0.
