Participants

Reaction Steps

In a manner similar to Paragraph E above, N-(5-chloropyridin-2-yl)-2-[((4-(chloromethyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide (1.0 g, 2.0 mmol) in DMF (5 mL) was reacted with dimethylamine (1.33 M in tetrahydrofuran, 7.5 mL, 10 mmol) to give N-(5-chloropyridin-2-yl)-2-[((4-((dimethylamino)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide; which was purified by lyophilization from aqueous HCl to afford N-(5-chloropyridin-2-yl)-2-[((4-((dimethylamino)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide; hydrochloric acid salt, as a white solid; NMR (DMSO-d6 /TFA) 10.9 (s, 1), 10.1 (br s, 1), 9.5 (s, 1), 8.3 (d, 1), 8.2 (s, 1), 8.1 (d, 1), 7.8 (dd, 1), 7.3 (dd, 2), 4.3 (br s, 2), 3.9 (s, 3), 2.8 (br s, 6) ppm.
