Reaction Steps

A mixture of 1,3-dipropyl-8-(1-prop-2-ynyl-1H-pyrazol-4-yl)-3,7-dihydro-purine-2,6-dione (200 mg, 0.59 mmol), 4-iodo-benzenesulfonamide (166 mg, 0.59 mmol), copper iodide (10 mg, 0.059 mmol), dichlorobis (triphenylphosphine)-palladium (II) (21 mg, 0.03 mmol), triethylamine (2 ml), DMF (2 ml) was degassed for 10 min. and stirred for 20 hrs at room temperature. The reaction mixture was diluted with water (10 ml) and extracted with DCM (3×10 ml). Organic layer was washed with brine (2×15 ml) and dried over Na2SO4. The organic volatile solvent was evaporated and the crude product was purified using HPLC to obtain pure 4-{3-[4-(2,6-dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-pyrazol-1-yl]-prop-1-ynyl}-benzenesulfonamide (4.2 mg, 2%).
