Reaction Conditions

Temperature	80 °C

Reaction Steps

1-(chloromethyl)-2-methylbenzene (0.045 ml) and potassium carbonate (0.6 g) were added to a solution of 5-methyl-2-(1-naphthylmethyl)-3-pyridin-4-yl-2H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione (2 ml). The mixture was heated at 80° C. for 18 hours then cooled to room temperature. Solids removed by filtration and the crude product was purified on preparative HPLC to give the title compound (0.057 g). Mass: 487.87 (M+H).
