Reaction Steps
5-Chloro-3-(4-chloro-3-(trifluoromethyl)phenylsulfonamido)picolinic acid (150 mg, 0.36 mmol), ethyl-pyridin-2-yl-amine (131 mg, 1.08 mmol), BOP (207 mg, 0.47 mmol), DIEA (400 L, 2.16 mmol) were reacted according to the procedure D to provide the title compound. HPLC purification (20→90% gradient of MeCN-water) provided 5-chloro-3-(4-chloro-3-trifluoromethyl-benzenesulfonylamino)-pyridine-2-carboxylic acid ethyl-pyridin-2-yl-amide: MS m/z: (M+H) 519.0.
