Procedure

Potassium carbonate (1.75 g, 12.7 mmol) was added to a solution of (RS)-1-(8-phenyl-1,4-dioxaspiro[4.5]decan-8-yl)-3-[3,5-bis(trifluoromethyl)phenyl]propan-1-yl ethanoate (Example 23, 410 mg, 0.773 mmol) in methanol (15 mL) and water (2 mL) and the mixture was stirred at room temperature for 48 hours, then at 50° C. for 24 hours. The mixture was cooled and the methanol was evaporated under reduced pressure. Water (50 mL) was added and the mixture was extracted with ethyl acetate (2×50 mL). The combined organic fractions were dried (Na2SO4) and the solvent was evaporated under reduced pressure to give the title compound (334 mg, 88%). 1H NMR (400 MHz, CDCl3) δ 7.68 (1H, s), 7.53 (2H, s), 7.4-7.3 (4H, m), 7.3-7.2 (1H, m), 3.95-3.8 (4H, m), 3.36 (1H, br d, J 9 Hz), 2.91 (1H, ddd, J 14, 10, 5 Hz), 2.64 (1H, ddd, J 16, 9, 7.5 Hz), 2.5-2.4 (1H, m), 2.3-2.2 (1H, m), 1.9-1.7 (3H, m) and 1.65-1.20 (6H, m).
