実験手順

10% Palladium on activated carbon (76 mg, 0.07 mmol, 0.1 eq) is added at room temperature to a stirred solution of 4-benzyloxy-6-methoxy-[1,5]naphthyridin-3-ylamine (200 mg, 0.71 mmol, 1.0 eq) in methanol (20 mL). The resulting mixture is stirred under hydrogen flow (3 bars) at room temperature for 16 hours. The catalyst is then removed by filtration and the solution is concentrated to give a residue that is purified by column chromatography (silica gel, eluent: dichloromethane:methanol, 50:1 to 10:1, v/v) to afford 3-amino-6-methoxy-[1,5]naphthyridin-4-ol as a yellow solid (39 mg, 29% yield).
