Reaction Steps

A mixture of 7-[(2,4-dichloro-5-methoxyphenyl)amino]-2-(1H-pyrazol-4-ylethynyl)thieno[3,2-b]pyridine-6-carbonitrile (57 mg, 0.13 mmol), 4-(2-chloroethyl)morpholine hydrochloride (24 mg, 0.13 mmol), and cesium carbonate (42 mg, 0.13 mmol) in 1 mL of dimethylformamide is heated at 50° C. overnight. The mixture is cooled to room temperature and then added to water. The resulting precipitate is collected by filtration. The collected solid is purified by flash column chromatography, eluting with 1:7 methanol:ethyl acetate to provide 50 mg of 7-[(2,4-dichloro-5-methoxyphenyl)amino]-2-{[1-(2-morpholin-4-ylethyl)-1H-pyrazol-4-yl]ethynyl}thieno[3,2-b]pyridine-6-carbonitrile as a yellow solid, mp greater than 200° C.; 1H NMR (DMSO-d6) δ 2.44 (br s, 4H), 2.62 (t, 2H), 3.53 (br s, 4H), 3.81 (s, 3H), 4.23 (br s, 2H), 6.77 (s, 1H), 7.57 (s, 1H), 7.71 (s, 1H), 7.80 (br, 1H), 8.24 (br, 1H), 8.37 (s, 1H), 13.36 (br s, 1H); MS 553.1 (M+H)+.
