PROCEDURE

实验过程

A solution of methyl 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((S)-1-hydroxybutan-2-yl)-3-methyl-2-oxopiperidin-3-yl)acetate (282 mg, 0.589 mmol; Example 186, Step A), 2-(tributylphosphoranylidene)acetonitrile (171 mg, 0.707 mmol) and di-tert-butyl iminodicarbonate (256 mg, 1.179 mmol) in toluene (3 mL) under argon was stirred at 110° C. for 2 h. Flash column purification on silica gel (0 to 60% EtOAc in hexanes) gave the title compound. Mass Spectrum (ESI) m/z=677 (M+1).
