الإجراء التجريبي

10% Palladium on activated carbon (976 mg, 0.91 mmol, 0.3 eq) is added at room temperature to a stirred solution of {trans-4-[5-(3-benzyloxy-6-methoxy-[1,5]naphthyridin-4-yl)-2-oxo-[1,3]dioxolan-4-ylmethyl]-cyclohexyl}-carbamic acid tert-butyl ester (1.70 g, 3.02 mmol, 1.0 eq) in methanol (200 mL), followed by several drops of triethylamine. The resulting mixture is stirred under hydrogen flow (1 bar) at room temperature for 1 hour. The catalyst is then removed by filtration and the solution is concentrated to afford {trans-4-[2-hydroxy-3-(3-hydroxy-6-methoxy-[1,5]naphthyridin-4-yl)-propyl]-cyclohexyl}-carbamic acid tert-butyl ester as a white solid (890 mg, 68% yield).
