A solution of N-(4-{4-amino-7-[(1E)-4-hydroxybut-1-enyl]thieno[3,2-c]pyridin-3-yl}-2-methoxyphenyl)-1-methyl-1H-indole-2-carboxamide (0.20 g, 0.40 mmol) in dichloromethane (10 mL) was treated with p-toluene sulfonyl chloride (0.100 g, 0.521 mmol), triethyl amine (0.08 g, 0.80 mmol), and dimethyl amino pyridine (0.003 g, 0.02 mmol). The reaction mixture was stirred at room temperature for 24 hours. No workup was used. The compound was purified by flash chromatography on silica gel using 1:1 ethyl acetate:heptane then 100% ethyl acetate to give 0.075 g (29%) the title compound. 1H NMR (CDCl3, 400 MHz) δ 8.70 (m, 1H), 8.60 (d, 1H), 7.90 (s, 1H), 7.80 (d, 1H), 7.70 (d, 1H), 7.45 (m, 1H), 7.40 (m, 1H), 7.30 (m, 2H), 7.21 (m, 2H), 7.19 (m, 1H), 7.10 (m, 1H), 7.05 (m, 1H), 6.60–6.50 (d, 2H), 6.15–6.10 (m, 1H), 4.95 (s, 2H), 4.20 (t, 2H), 4.12 (s, 3H), 3.98 (s, 3H), 2.70 (q, 2H), 2.39 (s, 3H); LCMS (conditions a) Rt 4.28 min (95%), M+ 653.4.
