Procedure

A mixture of 3-(2,3-dihydro-1H-indol-5-yl)furo[3,2-c]pyridin-4-amine (150 mg, 0.440 mmol), 2-fluoro-5-methylphenylacetic acid (78 mg, 0.464 mmol), HATU (185 mg, 0.487 mmol), and Hunig's base (0.31 mL, 1.775 mmol) in N,N-Dimethylformamide (DMF) (3 mL) was stirred at room temperature for 4 days. Water (10 mL) was added, the mixture was stirred for about an hour, and the precipitate was collected by vacuum filtration. The solid was dried in the vacuum oven overnight to give 3-{1-[(2-fluoro-5-methylphenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}furo[3,2-c]pyridin-4-amine (174 mg, 0.412 mmol, 94% yield) as a beige solid. LC/MS (ES) m/z=402 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 2.29 (s, 3H), 3.27 (t, J=8.34 Hz, 2H), 3.89 (s, 2H), 4.29 (t, J=8.46 Hz, 2H), 5.53 (s, 2H), 6.93 (d, J=6.06 Hz, 1H), 7.03-7.18 (m, 3H), 7.30 (d, J=8.08 Hz, 1H), 7.40 (s, 1H), 7.86 (d, J=5.81 Hz, 1H), 7.92 (s, 1H), 8.13 (d, J=8.08 Hz, 1H).
