関与物質

反応手順

To a solution of 3-hydroxy-2-(hydroxymethyl)pyridine (10.00 g) and KOH (7.00 g) in anhydrous EtOH was added benzyl bromide (7.30 mL) at room temperature under stirring. The reaction mixture was heated to reflux for 24 h, then cooled to rt and filtered. The filtrate was concentrated in vacuo and the residue was chromatographed with a silica gel column (eluting agent: 20:1 (v/v) DCM/MeOH) to give the title compound as a pale yellow solid (7.50 g, 65.00%), HPLC: 95.00%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 216.4 (M+1); 1H NMR (400 MHz, CDCl3) δ: 4.39 (br s, 1H), 4.82 (s, 2H), 5.11 (s, 2H), 7.16-7.17 (m, 2H), 7.34-7.40 (m, 5H), 8.15-8.17 (m, 1H) ppm.
