Procedure

To a mixture of 1,2,3-triazole (50 μL, 0.81 mmol) and cesium hydroxide monohydrate (18 mg, 0.11 mmol) in 1-methyl-2-pyrrolidinone (5 mL) is added slowly 7-[(2,4-dichloro-5-methoxyphenyl)amino]-2-ethynylthieno[3,2-b]pyridine-6-carbonitrile (200 mg, 0.54 mmol). The mixture is heated to 120° C. for 12 hours, cooled to room temperature and partitioned between water and ethyl acetate. The organic layer is washed with water, dried over sodium sulfate, and concentrated in vacuo. The residue is purified by flash column chromatography eluting with a gradient of methanol in dichloromethane (0–2%) to provide 90 mg (38%) of 7-[(2,4-dichloro-5-methoxyphenyl)amino]-2-[(E)-2-(2H-1,2,3-triazol-2-yl)vinyl]thieno[3,2-b]pyridine-6-carbonitrile as a yelllow solid, mp 315–316° C.; 1H NMR (DMSO-d6-TFA) δ 3.88 (s, 3H), 7.50 (s, 1H), 7.65 (d, J=14 Hz, 1H), 7.85 (s, 1H), 7.88 (s, 1H), 8.15 (s, 2H), 8.32 (d, J=14 Hz, 1H), 9.01 (s, 1H); MS 443.0 (M+H)+.
