Procedure

A mixture of 8-(4-Hydroxy-phenyl)-1-propyl-2-(3-trifluoromethyl-phenyl)-7-(2-trimethylsilanyl-ethoxymethyl)-1,7-dihydro-purin-6-one (0.115 g, 0.21 mmol), potassium carbonate (0.067 g, 0.48 mmol), 1-(3-bromo-prop-1-ynyl)-4-fluoro-benzene (0.67 g, 0.27 mmol) and acetone (10 ml) was heated at 60° C. for 2 hours. The mixture was cooled to room temperature and filtered through sintered funnel, washed with acetone. Solvent was evaporated and the residue was purified by preparative TLC to obtain pure 8-{4-[3-(4-Fluoro-Phenyl)-prop-2-ynyloxy]-phenyl}-1-propyl-2-(3-trifluoromethyl-phenyl)-7-(2-trimethylsilanyl-ethoxymethyl)-1,7-dihydro-purin-6-one (0.061 g, 43%) as pale yellow oil.
