Procedure

The compound of Example 13, 5-(5-hydroxypent-1-ynyl)-3-methyl-1-(2-methylpropyl)-6-(1-naphthalenylmethyl)-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (75 mg) was suspended in ethanol (50 ml). A suspension of 10% palladium on carbon (7 mg) in ethanol (3 ml) was added and the mixture was hydrogenated. When hydrogen uptake ceased, the reaction mixture was filtered and the solvent was removed by rotary evaporation. The crude product was purified by chromatography on silica eluting with ethyl acetate:isohexane (3:1) to give the title compound (29 mg) as an oil.
