実験手順
To a stirred solution of 3-{2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-ethyl]-1H-pyrrolo[2,3-b]pyridin-5-yl}-propane-1,2-diol (prepared as in Example 11, 70 mg, 0.16 mmol) in 50% aqueous tetrahydrofuran (10 mL) was added sodium metaperiodate (40 mg, 0.19 mmol) at 0° C. The resulting mixture was stirred at room temperature for 2 h, extracted with ethyl acetate, washed with brine, dried over anhydrous sodium sulfate. The solvent was evaporated in vacuo to give {2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-ethyl]-1H-pyrrolo[2,3-b]pyridin-5-yl}-acetaldehyde (65 mg, quant.) as a light yellow solid: LC/MS m/e calcd for C23H26N2O3S [M+H]+ 411.54, observed 411.1.
