Procedure
A solution of 4-(2,4-dichlorophenyl)-2-(2-fluoropyridin-4-yl)-5-(1H-1,2,3-triazol-5-yl)thiophene-3-carbonitrile (0.103 g, 0.247 mmol), 2,4-dimethoxybenzylamine (0.247 g, 1.48 mmol) and DIPEA (0.0959 g, 0.742 mmol) in 1-Butanol (15 g, 2.0E2 mmol) was irradiated in microwave at 170° C. for 2 hrs. The mixture was concerntrated and the residue was purified by column chromatography to afford desired intermediate. LC/MS (FA) ES+ 563, 565. To the intermediate in DCM (5.9 mL, 93 mmol) was added TFA (2 mL, 20 mmol) and the mixture was stirred for 10 min. The reaction mixture was concerntrated and the residue in MeOH was treated with sodium bicarbonate and water. The mixture was concentrated and the mixture was purified by column chromatography to afford the title compound (48 mg, 47.0%). LC/MS (FA) ES+ 413, 415. 1H NMR (400 MHz, d4-methanol) δ: 8.03 (1H, d, J=6.26 Hz), 7.74 (1H, d, J=1.93 Hz), 7.54 (1H, dd, J=8.27, 1.97 Hz), 7.46 (1H, d, J=8.26 Hz), 7.05 (1H, s), 7.01 (2H, m)
