Procedure

DIAD (0.955 ml, 4.91 mmol) was added to a stirred mixture of 2-[(1S,2R)-2-{1-[5-(ethoxymethyl)pyrimidin-2-yl]piperidin-4-yl}cyclopropyl]ethanol (1 g, 3.27 mmol), methyl (2-fluoro-4-hydroxyphenyl)acetate (0.724 g, 3.93 mmol) and triphenylphosphine (1.288 g, 4.91 mmol) in toluene (10 ml). The mixture was stirred at RT for 5 hrs. The mixture was diluted with ethyl acetate (20 mL), washed with brine, dried over MgSO4, filtered and the solvent evaporated in vacuo. The residue was purified by column chromatography on silica gel, Biotage 100M, using a gradient eluant of 0-100% EtOAc/hexanes to afford the title compound. LC/MS (m/z): 472 (M+H)+.
