Reaction Steps

3-[(3-Hydroxypropyl)thio]-5-methyl-7-(2-methylpropyl)-1H-pyrazolo[3,4-d]-pyrimidine-4,6(5H,7H)-dione (94 mg), potassium carbonate (90 mg) and 2-(phenylsulfonylmethyl)benzyl bromide (105 mg) were combined in dimethylsulfoxide (11 ml). After 5 hours at room temperature the reaction mixture was diluted with ethyl acetate and washed thrice with water, twice with dilute hydrochloric acid, once with brine, then dried over magnesium sulfate and then concentrated in vacuo. Chromatography on silica gel (isohexane:isopropanol 4:1) gave the title compound (70 mg).
