Reaction Steps

A mixture of 2-methyl-1-(pyrimidin-5-ylmethyl)-1H-indole-3-carboxylic acid (60 mg, 0.22 mmol), 1-ethyl-3-(3-dimethyllaminopropyl)carbodiimide hydrochloride (65 mg, 0.34 mmol), N-hydroxybenzotrizole (180 mg, 1.33 mmol) and triethylamine (46 mg, 0.34 mmol) in dichloromethane (30 mL) was stirred for 30 minutes at room temperature. Then to the mixture, 3-(aminomethyl)-4,6-dimethyl pyridin-2-ol (33.44 mg, 0.22 mmol) was added. The resultant mixture was stirred at room temperature for 12 hours. Then the mixture was washed with water (20 mL×3). The organic layer was concentrated to give a residue which was purified by column chromatography (silica gel, dichloromethane/methanol=20:1) to give N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-2-methyl-1-(pyrimidin-5-ylmethyl)-1H-indole-3-carboxamide (17 mg, 19%). LRMS (M+H+) m/z: calcd 401.19. found 401. HPLC purity (214 nm): 92%. 1H. NMR (300 MHz, CD3OD): δ 9.03 (s, 1H), 8.43 (s, 2H), 7.80-7.78 (m, 1H), 7.39-7.36 (m, 1H), 7.19-7.16 (m, 2H), 5.56 (s, 2H), 4.55 (s, 2H), 2.62 (s, 3H), 2.42 (s, 3H), 2.45 (s, 3H).
