1,3-Dimethyl-5-(1-methyl-1H-pyrazol-3-yl)-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (800 mg, 3.09 mmol), 4-bromo-N-methoxy-N-methylbutanamide (Intermediate P) (843 mg, 4.01 mmol) and cesium carbonate (2011 mg, 6.17 mmol) were suspended in DMF (11.100 ml) and the mixture was stirred at room temperature for 22 hours. The mixture was poured into water (50 ml) and extracted with DCM (3×100 ml). The combined organic extracts were washed with water (2×50 ml) and brine (50 ml), dried over sodium sulfate and evaporated under vacuum. Purification by mass-directed HPLC under the following conditions afforded the title compound.
