실험 절차

To a mixture of (4,5-difluoro-2-nitro-phenyl)-methanol (Example 72f, 5.1 g), (4R,7S)-4-(3-Bromo-5-ethoxy-4-hydroxy-phenyl)-2-methyl-5-oxo-7-propyl-1,4,5,6,7,8-hexahydro-quinoline-3-carbonitrile (Example 72e, 10.0 g) and polymer-supported triphenylphosphine (13.5 g, 3 mmol/g loading) in THF (500 ml), cooled to 0° C., was added diisopropyl azodicarboxylate (DIAD) (5.3 ml). After 1.5 h, the mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by chromatography on silicagel in heptane/ethyl acetate 4/1-2/3 (v/v) as eluent.
