A mixture of (3-(benzyloxy)pyridin-2-yl)methanol (7.50 g) and MnO2 (30.00 g) in CHCl3 was heated to reflux for 90 min, and then cooled to rt. The reaction mixture was filtered. The filtrate was concentrated in vacuo and the residue was chromatographed with a silica gel column (eluting agent: 2:1 (v/v) PE/EA) to give the title compound as a pale yellow solid (5.40 g, 73.00%), HPLC: 93.00%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 214.6 (M+1); 1H NMR (400 MHz, CDCl3) δ: 5.26 (s, 2H), 7.34-7.47 (m, 7H), 8.41 (t, J=2.5 Hz, 1H), 10.40 (s, 1H) ppm.
