Procedure

N-(4-{4-{[(1E)-(dimethylamino)methylene]amino}-7-[(thien-2-ylsulfonyl)amino]thieno[3,2-c]pyridin-3-yl}-2-methoxyphenyl)-1-methyl-1H-indole-2-carboxamide (prepared by reaction of N-[4-(7-amino-4-{[(1E)-(dimethylamino)methylene]amino}thieno[3,2-c]pyridin-3-yl)-2-methoxyphenyl]-1-methyl-1H-indole-2-carboxamide with 2-thiophenesulfonyl chloride according to General Procedure G) (0.021 g, 0.033 mmol) was dissolved in dioxane (1 mL), and aqueous hydrochloric acid (6 M, 1 mL) was added. The mixture was stirred at 50° C. for 13 h, cooled to ambient temperature, and quenched with aqueous sodium carbonate (1 M, 10 mL). The mixture was extracted with methanol/dichloromethane (1:9, 3×20 mL), and the combined organic fractions were dried over magnesiuin sulfate, filtered, and concentrated. Purification of the residue by flash column chromatography on silica gel which had been deactivated with triethylamine (10% by volume of silica gel used) afforded the title compound as a white foam (0.0085 g, 45%): 1H NMR (DMSO-d6, 400 MHz) δ 9.70 (br, 1H), 9.49 (s, 1H), 7.97 (d, 1H), 7.80 (m, 1H), 7.70 (d, 1H), 7.58 (d, 1H), 7.47 (s, 1H), 7.40 (m, 1H), 7.37 (s, 1H), 7.34 (m, 2H), 7.17 (s 1H), 7.14 (d, 1H), 7.07 (m, 2H), 5.35 (br, 2H), 4.03 (s, 3H), 3.09 (s, 3H); MS: (M−H)− 588.
