実験手順

A solution of (1S,2S) and (1R,2R)-methyl-3-((-5′-fluoro-2-(4-iodophenyl)-2-isopropyl-2′-oxospiro[cyclopropane-1,3′-indoline]-1′-yl)methyl)benzoate (1.35 g, 2.4 mmol), NaCN (240 mg, 4.9 mmol), CuI (50 mg, 0.3 mmol) and Pd(PPh3)4 (140 mg, 0.12 mmol) in tetrahydrofuran (9.0 mL) was stirred at 65° C. for 2 hours. The mixture was cooled to room temperature and extracted with ethyl acetate and washed with brine, dried over anhydrous sodium sulfate, concentrated in vacuo. Purification by flash column chromatography eluting with Hexane/ethyl acetate (8:1 to 4:1) to afford light yellow oil (500 mg, yield 45.5%) LC/MS m/e calcd. for C29H25FN2O3: 469, observed (M+H)+: 469.2
