Procedure

In a manner similar to Paragraph A above, N-(5-chloropyridin-2-yl)-2-[((4-(chloromethyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide (2.0 g, 4.0 mmol) was reacted with 2-aminoimidazole (1.3 g, 16 mmol) to give N-(5-chloropyridin-2-yl)-2-[((4-((2-aminoimidazol-1-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide, which was purified by HPLC on a C18 Vydac column with acetonitrile in water gradient with 0.1% trifluoroacetic acid to afford N-(5-chloropyridin-2-yl)-2-[((4-((2-aminoimidazol-1-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide, trifluoroacetic acid salt, as a white solid; NMR (DMSO-d6 /TFA) 10.9 (s, 1), 10.4 (s, 1), 8.3 (d, 1), 8.1 (d, 1), 7.9 (dd, 1), 7.8 (br, 1), 7.6 (s, 1), 4 (d, 1), 7.3 (d, 1), 6.9 (dt, 1), 5.0 (s, 2), 4.8 (s, 3) ppm.
