Reaction Steps
Dimethylamine (40% aqueous, 0.51 mL, 4.1 mmol) was dissolved in DMF (2 mL) under nitrogen, and N-(5-chloropyridin-2-yl)-2-[((4-((5-trichloromethyl-1,2,4-oxadiazol-3-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide (0.151 g, 0.23 mmol) was added. The reaction mixture was stirred for 40 minutes at ambient temperature, then poured into water (40 mL). The aqueous layer was extracted with ethyl acetate (3×25 mL). The combined organic layers were washed with water (3×25 mL), brine (25 mL), dried over magnesium sulfate, concentrated in vacuo, and dried under vacuum. The crude product was purified by flash chromatography on silica gel, eluting with 75% ethyl acetate/hexanes to afford N-(5-chloropyridin-2-yl)-2-[((4-((5-(dimethylamino)-1,2,4-oxadiazol-3-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-3-methoxy-5-chlorobenzamide; NMR (DMSO-d6) 10.9 (br, 1), 9.4 (br, 1), 8.4 (d, 1), 8.1 (d, 1), 7.9 (dd, 1), 7.8 (s, 1), 7.4 (d, 1), 7.2 (d, 1), 3.9 (s, 3), 3.8 (s, 2), 3.0 (s, 6) ppm.
