실험 절차

To a solution of 2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxopiperidin-1-yl)butanoic acid (81 mg, 0.176 mmol) (Example 101, Step A) in dry DMF (880 μL) with 3 eq TEA (73.6 μL, 0.528 mmol) at 0° was added 2 eq HATU (134 mg, 0.352 mmol). The reaction was stirred at 0° for 5 min, followed by addition of t-butyl amine (25.7 mg, 0.352 mmol). It was stirred for 30 min at 0°, quenched with sat. NaHCO3 and extracted to EtOAc. The combined organic layers were washed with sat. NaCl solution, dried over Na2SO4, filtered and the filtrate was concentrated. Purification of the residue by flash chromatography on silica gel (eluent: 0-30% EtOAc/hexanes, gradient elution) provided the title compound as a mixture of stereoisomers.
