実験手順

Diisopropylethylamine (0.6 mL, 3.4 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; 150 mg, 0.36 mmol) in tetrahydrofuran (5 mL), and the mixture was stirred at room temperature for 30 min. 3,5-Dichlorobenzenesulfonyl chloride (available from Sigma-Aldrich; 133 mg, 0.54 mmol) was added and the mixture was stirred at room temperature for 16 h. The solvent was evaporated under reduced pressure. Ethyl acetate was added and the mixture was washed with aqueous NaHCO3 (5 mL) and water (5 mL). The organic layer was dried over Na2SO4, filtered, and evaporated under reduced pressure. The residue was purified by chromatography on silica gel using a Biotage purification system, eluting with 10% ethyl acetate/hexanes, to give {4-[1-(3,5-dichloro-benzenesulfonyl)-piperidin-4-yl]-6-fluoro-naphthalen-2-yl}-acetic acid methyl ester (78 mg, 42%) as a sticky off-white solid. MS cald. for C24H23Cl2FNO4S [(M+H)+]: 510, obsd. 510.2.
