5-Chlorothiophene-2-sulfonyl chloride → 5-Chloro-thiophene-2-sulfonic acid[5-chloro-2-(2-fluoro-6-methoxy-benzoyl)-pyridin-3-yl]-amide

Participants

Reaction Steps

(3-Amino-5-chloro-pyridin-2-yl)-(2-fluoro-6-methoxy-phenyl)-methanone (50 mg, 0.178 mmol) and 5-chloro-thiophene-2-sulfonyl chloride (85 mg, 0.392 mmol) were reacted according to the procedure described in example 94. The crude product was purified by flash chromatography on silica gel using Combi-flash and pure product fractions were dried under reduced pressure to provide 5-chloro-thiophene-2-sulfonic acid [5-chloro-2-(2-fluoro-6-methoxy-benzoyl)-pyridin-3-yl]-amide. MS m/z: 460.9 (M+H).
