Procedure

To a mixture of N-(5-chloropyridin-2-yl)-2-[((4-((2-aminoimidazol-1-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide (0.053 g, 0.96 mmol) and sulfuric acid (0.10 g, 1.06 mmol) in methanol (10 mL) was added N-chlorosuccinimide (0.192 g, 1.43 mmol). After stirring at ambient temperature for 6 hours, the reaction was poured into water and extracted with ethyl acetate. The ethyl acetate extract was dried over sodium sulfate, concentrated in vacuo, and purified by flash chromatography on silica gel to give 0.33 g of N-(5-chloropyridin-2-yl)-2-[((4-((cis4,5-dimethoxy-2-iminotetrahydroimidazol-1-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide; NMR (CDCl3) 9.0 (d, 2), 8.3 (d, 1), 8.1 (d, 1), 7.7 (dd, 1), 7.5 (s, 1), 7.3 (d, 1), 7.1 (d, 1), 6.0 (br s, 1), 4.8 (m, 2), 4.6 (d, 1), 4.3 (d, 1), 3.9 (s, 3), 3.4 (s, 3), 3.3 (s, 3) ppm.
