実験手順

2-((1S,2R)-2-(1-(3-isopropyl-1,2,4-oxadiazol-5-yl)piperidin-4-yl)cyclopropyl)ethanol (1.7 g, 6.08 mmol), methyl 2-(4-hydroxyphenyl)acetate (1.5 g, 9.1 mmol) and triphenylphosphine (2.4 g, 9.1 mmol) were dissolved in THF (30 ml). The mixture was stirred at RT under N2 for 5 min and disisopropyl azodicarboxylate (1.78 ml, 9.1 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 silica gel column (100 g SNAP, 5-25% EtOAc in hexane) to afford the desired product. LC/MS (m/z): 428 (M+H)+.
