Reaction Steps

To a solution of 8-(4-Benzyloxy-phenyl)-1-propyl-2-(3-trifluoromethyl-phenyl)-7-(2-trimethylsilanyl-ethoxymethyl)-1,7-dihydro-purin-6-one (0.217 g, 0.24 mmol) in DMF:water (2.5 ml), 10% Pd/C (0.120 g) and ammonium formate (0.431 g, 6.8 mmol) were added and refluxed at 80° C. for 2 hours. The mixture was cooled and filtered through celite bed, solvent was evaporated and the residue was diluted with water (10 ml), acidified with citric acid and extracted with ethyl acetate (3×10 ml). The organic layer was washed with brine (2×15 ml). It was dried over Na2SO4 and the solvent was evaporated to obtain off white solid of 8-(4-Hydroxy-phenyl)-1-propyl-2-(3-trifluoromethyl-phenyl)-7-(2-trimethylsilanyl-ethoxymethyl)-1,7-dihydro-purin-6-one (0.237 g, quantitative).
