実験手順

To a solution of rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid trifluoroacetic acid prepared in Example 4 (0.33 g, 0.57 mmol) in 1,2-dichloroethane (30 mL) was added diisopropylethylamine (0.59 g, 4.6 mmol), diphenylphosphinic chloride (Aldrich) (0.54 g, 2.3 mmol) respectively. The mixture was stirred at room temperature for 0.5 h, then 4-amino-1-methyl-pyridin-2-one (Molbridge) (0.07 g, 0.57 mmol) was added. The reaction mixture was heated and stirred at 60° C. for 10 h. The mixture was concentrated. The residue was partitioned between ethyl acetate and water. The organic layer was separated, washed with water, brine, dried over Na2SO4, then concentrated. The residue was purified by chromatography (5-10% of MeOH in EtOAc) to give rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid (1-methyl-2-oxo-1,2-dihydro-pyridin-4-yl)-amide as a off white solid (32 mg, 10%).
