실험 절차

A mixture of 1-Propyl-8-(1H-pyrazol-4-yl)-2-pyrrolidin-1-yl-7-(2-trimethylsilanyl-ethoxymethyl)-1,7-dihydro-purin-6-one (0.111 g, 0.25 mmol), potassium carbonate (0.052 g, 0.38 mmol), 1-(3-bromo-prop-1-ynyl)-4-fluoro-benzene (0.69 g, 0.33 mmol) was taken in acetone (10 ml). The reaction mixture was heated at 80° 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-{1-[3-(4-Fluoro-phenyl)-prop-2-ynyl]-1H-pyrazol-4-yl}-1-propyl-2-pyrrolidin-1-yl-7-(2-trimethylsilanyl-ethoxymethyl)-1,7-dihydro-purin-6-one (0.025 g, 22%) as colourless oil.
