実験手順
To a rapidly stirred solution of (2S)-2′-oxo-1′-{[2-(trimethylsilyl)eth-oxy]methyl}-1,1′,2′,3-tetrahydrospiro[cyclopenta[b]quinoline-2,3′-pyrrolo[2,3-b]pyridine]-7-carbohydrazide from Step H (317 mg, 0.667 mmol) in DCM (6.8 mL) was added water (2.7 mL) plus concentrated aqueous NH4OH (0.6 mL) and lastly potassium ferricyanide (549 mg, 1.67 mmol). After 4.5 hours the reaction was diluted with water (20 mL) and DCM (40 mL). The aqueous layer was extracted once with DCM (20 mL). The combined organics were washed successively with water then half-saturated brine and then dried over sodium sulfate. The organics were then filtered, concentrated in vacuo, and applied to a silica gel column for purification, eluting with a gradient of CH2Cl2:MeOH—99:1 to 90:10. Clean product-containing fractions were pooled and concentrated in vacuo to give the title compound. MS: m/z=446 (M+1).
