Trifluromethanesulfonic anhydride (0.576 mL, 3.41 mmol) in DCM (3 mL) was added slowly to a solution of 6-(3-(4-chlorothiazol-2-yl)-3-hydroxypropyl)-1,3-dimethyl-5-phenyl-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (490 mg, 1.137 mmol) and triethylamine (0.792 mL, 5.69 mmol) in DCM (40 mL) at 0° C. Further portions of triethylamine (0.792 mL, 5.69 mmol) and trifluoromethanesulfonic anhydride (0.576 mL, 3.41 mmol) were added to allow the reaction to run to completion. The reaction was quenched with saturated NaHCO3(aq) and extracted with DCM. The organic phase was passed through a hydrophobic frit and evaporated under vacuum. Purification by mass-directed HPLC under the following conditions afforded the title compound.
