Reaction Steps
Sodium borohydride (4 mg, 0.11 mmol), followed by MeOH (0.25 mL), was added to a solution of {(Z)-4-[(R)-2-oxo-6-((E)-3-oxo-4-phenyl-but-1-enyl)-piperidin-1-yl]-but-2-enyloxy}-acetic acid methyl ester (28 mg, 0.073 mmol) in CH2Cl2 (0.75 mL) at 0° C. The mixture was allowed to warm to rt. After 1 h at rt, the reaction was quenched with aqueous HCl (0.5 M) and extracted with EtOAc (3×10 mL). The combined organic phase was dried (Na2SO4), filtered and concentrated in vacuo to afford 22 mg (78%) of the title compound.
