実験手順

Methyl (4-hydroxyphenyl)acetate (37 mg, 0.22 mmol), 1-methylcyclopropyl 4-[(1R,2S)-2-(2-hydroxyethyl)cyclopropyl)piperidine-1-carboxylate (60 mg, 0.22 mmol), and triphenylphosphine (88 mg, 0.34 mmol) were dissolved in tetrahydrofuran (1 mL) under an atmosphere of nitrogen and cooled at 0° C. DIAD (68 mg, 0.34 mmol) was added and the resulting mixture was warmed to RT and stirred overnight. The mixture was diluted with ethyl acetate (10 mL) and water (5 mL), and the layers were separated. The organic layer was washed with brine (2×10 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography (24 g of silica gel, ISCO, eluted with a gradient 0-100% ethyl acetate in Hexane) to afford the title compound. HPLC/MS; 1.27 min, 438 (M+Na)+.
