Procedure

To [2-fluoro-6-(4-methoxy-benzylamino)-pyridin-3-yl]-methanol (64, 63 g, 240 mmol) in 1.25 L of ethyl acetate, manganese(IV) oxide (210 g, 2.416 mol) was added. The reaction was stirred overnight at room temperature, then filtered through celite and the celite rinsed with ethyl acetate. The combined filtrates were concentrated under vacuum and the resulting solid was triturated with heptane and collected by filtration to provide the desired compound as a white solid (65, 62 g, 238 mmol, 99% yield).
