Procedure
Triethylamine (0.04 mL) followed by isobutylchloroformate (0.033 g) were added to a solution of 3-[7-isobutyl-5-methyl-2-(1-naphthylmethyl)-4,6-dioxo-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-d]pyrimidin-3-yl]benzoic acid (0.08 g) in THF (1 mL) at 0° C. The mixture was stirred at 0° C. for 1 hour. Methylamine (2M, 2 mL) was added and the mixture was stirred at 0° C. for 1 h, then at room temperature for 2 h. Reaction was diluted with water (10 mL) and extracted with dichloromethane (2×10 mL). Combined organic layers were dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure. The residue was purified on preparative HPLC to give the title compound (0.027 g).
