実験手順
To a solution of 1-[2-chloro-7-(1-ethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidin-6-yl]-ethanol (61 mg, 0.2 mmol) in CH2Cl2 (2 mL) is added Dess-Martin periodinane (242 mg, 0.5 mmol). The reaction mixture is stirred for 1 h, quenched with 10% NaS2O3:saturated NaHCO3 (1:1) aqueous solution, and extracted with CH2Cl2. The extracts are washed with water and brine, dried over Na2SO4, and concentrated in vacuo. The residue is purified by flash chromatography (SiO2, EtOAc/Hexane 1:3) to afford 58 mg of 1-[2-chloro-7-(1-ethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidin-6-yl]-ethanone.
