実験手順

DBU (6.6 μL, 0.044 mmol) was added to a solution of (4-{(R)-2-[(E)-4-(3-chlorophenyl)-3-hydroxy-but-1-enyl]-6-oxo-piperidin-1-yl}-but-2-ynyloxy)-acetic acid (12 mg, 0.030 mmol) in acetone (0.3 mL). After 5 min, 2-iodopropane (15 μL, 0.15 mmol) was added. After 19 h, the reaction mixture was concentrated in vacuo, 0.5 M aqueous HCl (5 mL) was added and the mixture was extracted with EtOAc (3×5 mL). The combine organic phase was washed with saturated aqueous NaHCO3 (10 mL) and brine (10 mL) then dried (MgSO4), filtered and concentrated in vacuo. Purification of the residue by flash column chromatography on silica gel (CH2Cl2→3% MeOH/CH2Cl2, gradient) afforded 7.9 mg (60%) of the title compound.
