실험 절차

To 6-[(3-chloro-pyridin-4-ylmethyl)-amino]-pyridin-3-yl-methanol (556, 0.50 g, 2.00 mmol) in tetrahydrofuran (20.0 mL) was added Dess-Martin periodinane (1.02 g, 2.40 mmol). The reaction was stirred at room temperature for 10 minutes, then poured into aqueous potassium carbonate, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated to give crude compound (557, 0.45 g, 91%) that was used in the next step without further purification.
