Methanesulfonyl chloride → 4-amino-3-(3-methoxy-4-{[(1-methyl-1H-indol-2-yl)carbonyl]amino}phenyl)-N-[1-(methylsulfonyl)piperidin-3-yl]thieno[3,2-c]pyridine-7-carboxamide

Participants

Reaction Steps

A mixture of 4-amino-3-(3-methoxy-4-{[(1-methyl-1H-indol-2-yl)carbonyl]amino}phenyl)-N-piperidin-3-ylthieno[3,2-c]pyridine-7-carboxamide (150 mg, 0.270 mmol), methanesulfonyl chloride (26 μL, 0.32 mmol) and N,N-diisopropylethyl amine (0.15 mL, 0.81 mmol) in dichloromethane (5 mL) was stirred at room temperature for 2 hours. Saturated sodium bicarbonate (2 mL) was added. The layers were separated and the organic solvent was removed. The residue was purified by flash column chromatography on silica using dichloromethane/methanol/ammonium hydroxide (28–30% solution) (90:10:0.05) mixture as the mobile phase to give the title compound. 1H NMR (DMSO, d6) δ 1.58 (m, 2H), 1.91 (m, 2H), 2.58 (m, 1H), 2.71 (m, 1H), 3.50(m, 1H), 3.73 (m, 1H), 3.91 (s, 3H), 3.99 (m 1H), 4.04 (m, 3H), 7.07 (d, 1H), 7.15 (t, 1H), 7.19 (s, 1H), 7.33 (t, 1H), 7.35 (s, 1H), 7.58 (m, 2H), 7.71 (d, 1H), 7.99 (d, 1H), 8.34 (d, 1H), 8.61 (s, 1H), 9.50 (s, 1H).
