Procedure

N-{4-[4-amino-7-(4-formylphenyl)thieno[3,2-c]pyridin-3-yl]-2-methoxyphenyl}-1-methyl-1H-indole-2-carboxamide (Example 2, 0.030 g, 0.056 mmol) was dissolved in N,N-dimethylformamide (0.5 mL). Sodium borohydride (0.006 g, 0.167 mmol) and methanol (0.5 mL) were added, and the reaction mixture was stirred at ambient temperature for 16 h. The mixture was diluted with aqueous sodium carbonate (1 M, 10 mL) and the product was extracted with methanol dichloromethane (1:33, 3×20 mL). The organic fractions were combined, dried over magnesium sulfate, filtered, and concentrated. The residue was purified by flash column chromatography on silica gel, using ethyl acetate-heptane (3:1) as the mobile phase, to afford the title compound (0.011 g, 0.020 mmol) as a white powder. 1H NMR (DMSO-d6, 400 MHz) δ 9.53 (s, 1H), 8.00 (d, 1H), 7.92 (s, 1H), 7.71 (s, 1H), 7.62 (m, 1H), 7.59 (s, 1H), 7.56 (m, 2H), 7.49 (t, 1H), 7.36 (s, 1H), 7.32 (m, 3H), 7.16 (d, 1H), 7.12 (m, 1H), 5.61 (br, 2H), 5.31 (t, 1H), 4.61 (d, 2H), 4.05 (s, 3H), 3.92 (s, 3H); MS: (M−H)− 533.
