반응 단계
5-Chloro-3-(4-chloro-3-(trifluoromethyl)phenylsulfonamido)picolinic acid (208 mg, 0.50 mmol), 1,2,3,4-tetrahydro-[1,8]naphthyridine [(135 mg, 1.0 mmol) 1,2,3,4-tetrahydro-[1,8]naphthyridine was prepared freshly from 1,8-napthyridine via hydrogenation over Pt2O], BOP (486 mg, 1.1 mmol), DIEA (185 mg, 1.4 mmol) were reacted according to the procedure D to provide the title compound. HPLC purification (20→90% gradient of MeCN-water) provided 4-chloro-N-[5-chloro-2-(3,4-dihydro-2H-[1,8]naphthyridine-1-carbonyl)-pyridin-3-yl]-3-trifluoromethyl-benzenesulfonamide: MS m/z: 531.0 (M+H).
