Reaction Steps
To a solution of N-(4-chlorophenyl)-2-[((4-(chloromethyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide (1.0 g, 2.1 mmol) in DMF (40 mL) at 0° C. was added 1-methylpiperazine (1.2 mL, 1.1 g, 11 mmol), and the mixture stirred for 0.5 hours at 0° C., then warmed to ambient temperature. After 7 hours the reaction mixture was poured into water (150 mL) and the resulting solid collected by filtration, washed with water (50 mL) and acetonitrile (10 mL). Purification by flash chromatography on silica gel afforded 0.77 g (64% yield) of N-(4-chlorophenyl)-2-[((4-((4-methylpiperazin-1-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide, as a white foam: NMR (DMSO-d6 /TFA) 10.4 (s, 1), 9.4 (s, 1), 7.2-8.1 (m, 7), 4.4 (s, 2), 3.8 (s, 3), 3.0-3.8 (br m, 8), 2.8 (s, 3) ppm.
