Methanesulfonic anhydride (0.679 g, 3.90 mmol) in 1,2-dichloroethane (3.0 mL) was added dropwise to a solution of DMAP (0.016 g, 0.130 mmol), triethylamine (0.544 ml, 3.90 mmol) and 6-(3-((tert-butyldimethylsilyl)oxy)-2-hydroxypropyl)-5-(3-fluorophenyl)-1,3-dimethyl-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (0.6 g, 1.300 mmol) in 1,2-dichloroethane (10 mL) at 0° C. The mixture was warmed to room temperature and stirred for 2 hours, then diluted with water (10 mL). The phases were separated and the aqueous phase was extracted with DCM (3×10 mL). The combined organic extracts were dried over magnesium sulfate and evaporated under vacuum to afford the title compound.
