実験手順
To tert-butyl-4-{3-[(3R)-3-{[(1S)-1-(5-hydroxypyridin-3-yl)-3-methoxy-3-oxopropyl]carbamoyl}piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate (30 mg, 60 μmol) in DMF (7.6 mL) was added cesium carbonate (44.7 mg, 140 μmol) and 2-[2-(2-fluoroethoxy)ethoxy]ethyl 4-methylbenzenesulfonate (25 mg, 80 μmol) while stirring at room temperature. After 5 hours toluene was added and the mixture was concentrated in vacuum. The DMF free residue was purified by preparative thin layer chromatography on silica gel (ethyl acetate) to yield 16.7 mg of tert-butyl 4-{3-[(3R)-3-{[(1S)-1-(5-{2-[2-(2-fluoroethoxy)ethoxy]ethoxy}pyridin-3-yl)-3-methoxy-3-oxopropyl]carbamoyl}piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate.
