실험 절차

10% Palladium on activated carbon (140 mg, 0.13 mmol, 0.1 eq) is added at room temperature to a stirred solution of (3-benzyloxy-6-methoxy-[1,5]naphthyridine-4-yl)-methanol (390 mg, 1.32 mmol, 1.0 eq) in methanol (30 mL). The resulting mixture is stirred under hydrogen flow (4 bars) at room temperature for 1 hour. The catalyst is then removed by filtration and the solution is concentrated to afford 4-hydroxymethyl-6-methoxy-[1,5]naphthyridin-3-ol as a white solid (220 mg, 81% yield).
