1,2-Dichloroethane → 6-bromo-N-((6-(hydroxymethyl)-2-methoxy-4-methylpyridin-3-yl)methyl)-1-isopropyl-3-methyl-1H-indole-4-carboxamide

Participants

Reaction Steps

To a stirred solution of (5-(aminomethyl)-6-methoxy-4-methylpyridin-2-yl)methanol (0.29 g, 1.591 mmol), 6-bromo-1-isopropyl-3-methyl-1H-indole-4-carboxylic acid (0.48 g, 1.621 mmol), and HOAt (0.22 g, 1.616 mmol) in Dichloromethane (15 mL) and DMF (5 mL) was added EDC free base (0.30 g, 1.932 mmol). The reaction was stirred at RT for 3 h then evaporated to dryness under vacuum. The remaining was purified by silica gel chromatography (Analogix, SF25-60 g, 0 to 20% EtOAc in CH2Cl2) to give the product 6-bromo-N-((6-(hydroxymethyl)-2-methoxy-4-methylpyridin-3-yl)methyl)-1-isopropyl-3-methyl-1H-indole-4-carboxamide (0.73 g, 1.586 mmol, 100% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ=8.46 (t, J=4.9 Hz, 1 H), 7.77 (d, J=1.8 Hz, 1 H), 7.33 (d, J=1.0 Hz, 1 H), 6.99 (d, J=1.5 Hz, 1 H), 6.90 (s, 1 H), 5.31 (t, J=5.9 Hz, 1 H), 4.74 (quin, J=6.6 Hz, 1 H), 4.45 (d, J=5.1 Hz, 1 H), 4.43 (d, J=5.8 Hz, 2 H), 3.83 (s, 3 H), 2.40 (s, 3 H), 2.10 (s, 3 H), 1.38 (d, J=6.8 Hz, 6 H). MS(ES)+m/e 460.2 [M+H]+.
