実験手順

To an ice-cooled solution of 1.15 g (2.49 mmol) of 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxo-1-(pentan-3-yl)piperidin-3-yl)acetic acid (Example 71, Step F) in THF (12.5 mL) was added 383 μL (3.48 mmol) of N-methylmorpholine and 392 μL (2.98 mmol) of isobutyl chloroformate. The resulting off-white slurry was stirred at 0° C. for 2 h, and then 336 μL (28% ammonia in water, 4.97 mmol) of ammonium hydroxide was added. After an additional 3 h at 0° C., the reaction was quenched with saturated aqueous ammonium chloride and extracted with EtOAc (3×). The combined organic layers were dried over Na2SO4, filtered and the filtrate was concentrated. The crude title compound was used directly in the next step.
