実験手順

To a mixture of 5-cyclopropyl-2-fluoro-4-((trans-4-methylcyclohexyl)-methoxy)benzoic acid (0.255 g, 0.83 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.242 g, 1.26 mmol) and 4-dimethylaminopyridine (0.242 g, 1.98 mmol) in anhydrous dichloromethane (22 mL) was added azetidine-1-sulfonamide (0.173 g, 1.27 mmol). The reaction mixture was stirred at ambient temperature for 16 hours. The mixture was poured into 5% aqueous hydrochloric acid (50 mL) and the layers were separated. The aqueous layer was extracted with ethyl acetate (4×50 mL). The combined organic layers were washed with water (50 mL) and brine (50 mL); dried over anhydrous sodium sulfate; filtered and concentrated in vacuo. The residue was purified by column chromatography (0% to 40% ethyl acetate in hexanes) to afford the title compound (0.114 g, 33%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ 8.66 (d, J=16.7 Hz, 1H), 7.59 (d, J=9.1 Hz, 1H), 6.57 (d, J=14.5 Hz, 1H), 4.25 (t, J=7.7 Hz, 4H), 3.83 (d, J=6.1 Hz, 2H), 2.27 (q, J=7.7 Hz, 1H), 2.11-2.02 (m, 1H), 1.92-1.75 (m, 5H), 1.41-1.29 (m, 1H), 1.25-0.90 (m, 10H), 0.70-0.64 (m, 2H); MS (ES−) m/z 423.26 (M−1).
