実験手順

In a vial, (S)-tert-butyl 1-(2-amino-4-(trifluoromethyl)phenyl)piperidin-3-yl(methyl)carbamate (0.500 g, 1.3 mmol) was taken up in CH2Cl2. The solution was cooled to 0 deg. C and Triethylamine (0.24 ml, 1.7 mmol) and 2-fluoro-5-iodobenzoyl chloride (0.42 g, 1.5 mmol) were added. The tube was sealed and the reaction stirred for 2 h. The reaction mixture was poured into EtOAc/1N NaOH. The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo. The resulting off-white foam (S)-tert-butyl 1-(2-(2-fluoro-5-iodobenzamido)-4-(trifluoromethyl)phenyl)piperidin-3-yl(methyl)carbamate was used without further purification. MS m/z=622 [M+H]+. Calc'd for C25H28F4IN3O3: 621.
