Trimethylsulfoxonium iodide (45.1 mg, 0.205 mmol) in anhydrous methyl sulfoxide (4 mL) and 60% sodium hydride in mineral oil (16.4 mg, 0.411 mmol) was stirred for 5 minutes at room temperature and treated with a mixture of ethyl (2E)-3-[4-amino-3-(3-methoxy-4-{[(1-methyl-1H-indol-2-yl)carbonyl]amino}phenyl)thieno[3,2-c]pyridin-7-yl]acrylate (108 mg, 0.205 mmol) in methyl sulfoxide (2 mL) was added. After 4 hours the mixture was cooled to room temperature and quenched with saturated ammonium chloride solution (7 mL). The aqueous layer was extracted with dichloromethane (3×10 mL), dried over magnesium sulfate, filtered, and the solvent was removed under reduced pressure. The crude product was purified via HPLC preparative to give the title compound as a white solid (33.6 mg 0.062 mmol): LCMS (Conditions a): MH+=541 Rt =4.20 minutes; 1H NMR (DMSO-d6, 400 MHz) δ 9.51 (1 H), 7.99 (1 H), 7.69 (2 H), 7.58 (2 H), 7.35 (2 H), 7.18 (1 H), 7.15 (1 H), 7.06 (1 H), 5.49 (1 H), 4.18 (2 H), 4.04 (3 H), 3.91 (3 H), 2.45 (1 H), 1.86 (1 H), 1.56 (1 H), 1.47 (1 H), 1.26 (3 H).
