Procedure

To a solution of N-(5-chloropyridin-2-yl)-2-[((4-(chloromethyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide (2.1 g, 4.1 mmol) in DMF (20 mL) was added a 2,2,2-trifluoroethylamine (3.2 mL, 41 mmol). The mixture was heated at 75° C. for 18 hours, then cooled to ambient temperature and concentrated in vacuo to remove excess 2,2,2-trifluoroethylamine. Water was added and the mixture was extracted with methylene chloride. The organic layer was dried over Na2SO4 and concentrated in vacuo. Purification by flash chromatography on silica gel afforded 2.2 g (95% yield) of N-(5-chloropyridin-2-yl)-2-[((4-(((2,2,2-trifluoroethyl)amino)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide; NMR (DMSO-dr/TFA) 10.8 (s, 1) 9.4 (s, 1), 8.2 (d, 1), 8.1 (d, 1), 8.0 (s, 1), 7.8 (dd, 1), 7.2 (d, 2), 4.2 (s, 2), 4.1 (q, 2), 3.8 (s, 3) ppm.
