実験手順

Diisopropylethylamine (0.3 mL, 1.7 mmol) was added at 0° C. to a solution of (6-fluoro-4-piperidin-4-yl-naphthalen-2-yl)-acetic acid methyl ester trifluoroacetate salt (which may be prepared as described above; 100 mg, 0.24 mmol) in CH2Cl2 (6 mL). The solution was stirred at room temperature for 30 min and then a solution of pyridine-4-sulfonyl chloride (which may be prepared as described above; 213 mg, 1.2 mmol) in CH2Cl2 (1 mL) was added. The mixture was stirred at room temperature for 16 h. The solvent was evaporated under reduced pressure. The residue was purified by chromatography on silica gel to give {6-fluoro-4-[1-(pyridine-4-sulfonyl)-piperidin-4-yl]-naphthalen-2-yl}-acetic acid methyl ester (45 mg, 42%) as an orange liquid. MS cald. for C23H24FN2O4S [(M+H)+]: 443, obsd. 443.4.
