실험 절차

To a stirred solution of tert-butyl ((5-(aminomethyl)-6-methoxy-4-methylpyridin-2-yl)methyl)carbamate (0.55 g, 1.955 mmol), 6-bromo-1-isopropyl-3-methyl-1H-indole-4-carboxylic acid (0.63 g, 2.127 mmol), and HOAt (0.27 g, 1.984 mmol) in Dichloromethane (20 mL) and DMF (5 mL) was added EDC free base (0.34 g, 2.190 mmol). The reaction was stirred at RT for 2 hr then evaporated to dryness under vacuum. The remaining was purified by silica gel chromatography (Analogix, SF25-60 g, 0 to 40% EtOAc in hexanes) to give the product tert-butyl ((5-((6-bromo-1-isopropyl-3-methyl-1H-indole-4-carboxamido)methyl)-6-methoxy-4-methylpyridin-2-yl)methyl)carbamate (1.07 g, 1.912 mmol, 98% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ=8.47 (t, J=4.8 Hz, 1H), 7.76 (d, J=1.8 Hz, 1H), 7.35 (t, 1H), 7.33 (d, J=1.0 Hz, 1H), 6.99 (d, J=1.5 Hz, 1H), 6.67 (s, 1H), 4.74 (quin, J=6.6 Hz, 1H), 4.44 (d, J=4.8 Hz, 2H), 4.08 (d, J=6.3 Hz, 2H), 3.85 (s, 3H), 2.37 (s, 3H), 2.10 (s, 3H), 1.41 (s, 9H), 1.38 (d, J=6.6 Hz, 6H).
