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 (example 5e, 200 mg, 0.37 mmol) in DMF (5 mL) was added sodium hydride (60%, 9.6 mg, 0.24 mmol) and the mixture was cooled to 0° C. 4-(Bromomethyl)-2-fluorobenzonitrile (70.5 mg, 0.33 mmol) in DMF (3 mL) was added while stirring and the mixture was warmed to room temperature. After one hour water, brine and ethyl acetate were added. Phases were separated and the aqueous phase was extracted with ethyl acetate. The combined extracts were dried over sodium sulfate and concentrated in vacuum. The residue was purified by preparative HPLC to yield 10 mg of tert-butyl 4-{3-[(3R)-3-{[(1S)-1-{5-[(4-cyano-3-fluorobenzyl)oxy]pyridin-3-yl}-3-methoxy-3-oxopropyl]carbamoyl}piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate.
