실험 절차

A solution of {4-[(R)-2-Oxo-6-((E)-3-oxo-4-phenyl-but-1-enyl)-piperidin-1-yl]-but-2-ynyloxy}-acetic acid methyl ester (30 mg, 0.078 mmol) in toluene (2 mL) was added via cannula to a round-bottomed flask containing hydrido(triphenylphosphine)copper(I) hexamer (154 mg, 0.078 mmol) at −40° C. under nitrogen. The reaction was allowed to warm to rt and stirred for 2.5 h. The reaction was quenched with NH4OH/NH4Cl (1:1, 8 mL) and extracted with EtOAc (3×10 mL). The combined extracts were dried washed with brine (10 mL) then dried (Na2SO4), filtered and concentrated in vacuo. Purification of the residue by flash column chromatography on silica gel (20% →40% EtOAc/CH2Cl2, gradient) afforded 23.4 mg (78%) of the title compound.
