실험 절차

Racemic (2′S,3S,4′R)-6-chloro-2′-(3-chlorophenyl)-4′-(5-fluoro-2-methyl-phenyl)-2,3-dihydro-2,6′-dioxospiro[indole-3,3′-piperidine]-1-methoxyethyl trimethylsilane (0.40 g, 0.67 mmol) prepared in example 146a was reacted with LiH (0.13 g, 16.70 mmol) and 1-chloro-3-bromo-propane (0.63 g, 4.01 mmol) in N,N-dimethyl-formamide (3 mL), a catalytic amount of KI. After the solution was stirred overnight, the solution was poured into water. The water layer was extracted with ethyl acetate and the combined organic layers were dried, concentrated to obtain the crude product. The crude product was purified by chromatography to give racemic (2′S,3S,4′R)-6-chloro-1′-(3-chloro-propyl)-2′-(3-chlorophenyl)-4′-(5-fluoro-2-methyl-phenyl)-2,3-dihydro-2,6′-dioxospiro[indole-3,3′-piperidine]-1-methoxyethyl trimethylsilane as a yellow solid (Yield: 0.11 g, 24%).
