실험 절차

To a mixture of 4-(adamantan-1-ylmethoxy)-5-cyclopropyl-2-fluorobenzoic acid (0.20 g, 0.60 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (0.26 g, 1.38 mmol) and 4-dimethylaminopyridine (0.17 g, 1.38 mmol) in anhydrous dichloromethane (10 mL) was added 3-cyanoazetidine-1-sulfonamide (0.22 g, 1.38 mmol) at ambient temperature. The resulting mixture was stirred at ambient temperature for 16 hours. The mixture was quenched with 1 M aqueous hydrochloride acid (30 mL) followed by extraction with ethyl acetate (100 mL). The organic layer was washed with water (30 mL), dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated in vacuo, the residue was purified by silica gel column chromatography using 10-60% ethyl acetate (containing 2% acetic acid) in hexanes as an elute to afford the title compound as colorless solid (0.23 g, 79%): 1H NMR (300 MHz, DMSO-d6) δ 11.88 (s, 1H), 7.18 (d, J=8.3 Hz, 1H), 6.95 (d, J=13.0 Hz, 1H), 4.35-4.22 (m, 4H), 3.84-3.74 (m, 1H), 3.65 (s, 2H), 2.09-1.99 (m, 4H), 1.75-1.67 (m, 12H), 0.95-0.87 (m, 2H), 0.70-0.65 (m, 2H); MS (ES+) m/z 488.2 (M+1); MS (ES−) m/z 486.3 (M−1).
