실험 절차

A solution of 1-{4-[3-Cyclopentyl-4-(2,2-dimethyl-6-oxo-6H-[1,3]dioxin-4-yl)-3-hydroxy-butyl]-2-fluoro-phenyl}-cyclopropanecarbonitrile (0.9 g, 2.1 mmol) from Step 6 below in NaOH (0.3 M in MeOH, 21 mL, 6.3 mmol) was stirred at room temperature for 3 hours. The reaction was then quenched with 100 mL saturated NH4Cl and 5 mL 1 N HCl. To this solution was added 100 mL CH2Cl2 and the layers were separated. The aqueous layer was extracted with 2×100 mL CH2Cl2 and the organic layers were combined. After drying the organic with MgSO4, and filtering to remove the solids, the solvent was removed by rotary evaporation. The remaining oil was purified by flash chromatography to yield the desired product (0.367 g, 47%). 1H NMR (CDCl3) δ: 1.27-1.30 (m, 2H), 1.51-1.73 (m, 10H), 1.84-1.89 (m, 2H), 2.19 (p, J=8.08 Hz, 1H), 2.58-2.71 (m, 4H), 3.36 (d, J=4.04 Hz, 2H), 6.81-6.86 (m, 2H), 7.16-7.18 (m, 1H). MS (ESI): 368 (M−H).
