Procedure

To a solution of methyl{2-fluoro-4-[2-((1S,2R)-2-{1-[5-(methoxymethyl)pyrimidin-2-yl]piperidin-4-yl}cyclopropyl)ethoxy]phenyl}acetate (1.50 g, 3.28 mmol) in 21 ml of tetrahydrofuran was added 14 ml of methanol and 14 ml of water. Lithium hydroxide (0.393 g, 16.4 mmol) was added to the mixture, and stirred at RT overnight. 1 M hydrochloric acid was added to adjust the pH to 4. The volatiles were removed in vacuo, and the remaining aqueous layer extracted with dichloromethane (3×30 ml). The organic fractions were combined, dried over magnesium sulphate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography (50 g silica gel) using a gradient eluent of 0-70% ethyl acetate in hexanes (1000 ml) to afford the title compound. LC/MS (m/z) 444.4 (M+H)+.
