Procedure

To a solution of tert-butyl 3-((7-chloropyrido[4,3-b]pyrazin-5-ylamino)methyl)-5-hydroxypiperidine-1-carboxylate (1.97 g, 5.0 mmol) in dichloromethane was added Dess-Martin periodinane (2.54 g, 6.0 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight, then diluted with ethyl acetate, washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo to give the title compound.
