実験手順

2-{(1S,2R)-2-[1-(5-Methoxypyrimidin-2-yl)piperidin-4-yl]cyclopropyl}ethanol (1.2 g, 4.33 mmol), methyl 2-(2-fluoro-4-hydroxyphenyl)acetate (0.956 g, 5.19 mmol) and triphenylphosphine (1.702 g, 6.49 mmol) were dissolved in dichloromethane (20 ml). The mixture was stirred at RT under N2 for 5 min and diisopropyl azodicarboxylate (1.274 ml, 6.49 mmol) was added. The mixture was stirred at RT overnight. The mixture was diluted with DCM (50 ml), washed with water, dried and evaporated. The crude material was purified by column chromatography on silica gel (50 g SNAP, 5˜30% EtOAc in hexane) to afford the desired product which contains some impurities. This material was re-purified by column chromatography on silica gel (50 g SNAP, 2˜5% EtOAc in DCM) to afford the title compound. LC/MS (m/z): 444 (M+H)+. Rf was 0.4 @ 30% EtOAc in hexanes (blue spot on CAM stain).
