実験手順

To a solution of tert-butyl (3R,4S)-3-({cyclopropyl[3-hydroxy-5-(3-methoxy-propyl)benzyl]amino}carbonyl)-4-{4-[2-(2,6-dichloro-4-methylphenoxy)ethoxy]-phenyl}piperidine-1-carboxylate (1 eq.) from Example 1/Step 2 in DMF (0.1 M) was added [1-(cyanomethyl)cyclopropyl]methyl methanesulfonate (appendage 4) (2 eq.) and cesium carbonate (2 eq.). The reaction was heated to 80° C. and stirred for 18 h. After cooling to rt, the reaction was diluted with ether. The organic extract was washed with water, brine, dried over MgSO4, and concentrated in vacuo. The crude product was purified by flash column chromatography (SiO2, 0%→50% EtOAc in toluene) to afford the title compound as an oil.
