Reaction Steps

7-benzyl-8-ethoxy-3-ethyl-1-(3-hydroxypropyl)-1H-purine-2,6(3H,7H)-dione (0.12 g, 0.323 mmol) was dissolved in ethanol (20 mL) and degassed and refilled with nitrogen three times. Ammonium formate (0.5 g, 7.94 mmol) and 10% Pd/C (30 mg) were added and the mixture was again degassed and refilled with nitrogen three times. The reaction was stirred at 80° C. overnight. Then the mixture was cooled, filtered and the filter cake was washed with methanol. The filtrate was concentrated to give 8-ethoxy-3-ethyl-1-(3-hydroxypropyl)-1H-purine-2,6(3H,7H)-dione (70 mg, 77.1% yield) as white solid. LCMS retention time 0.413 min; LCMS MH+ 283.
