Procedure

A mixture of 8-{4-[3-(4-Fluoro-phenyl)-prop-2-ynyloxy]-phenyl}-1-propyl-7-(2-trimethylsilanyl-ethoxymethyl)-1,7-dihydro-purin-6-one (0.03 g, 0.056 mmol), 2N HCl (1 ml), ethanol (2 ml) was heated at 85° C. for 2 hours. The mixture was cooled and the solvent was evaporated. The residue was washed with n-pentane to obtain 8-{4-[3-(4-fluoro-phenyl)-prop-2-ynyloxy]-phenyl}-1-propyl-1,7-dihydro-purin-6-one (0.018 g, 78%) as off white solid.
