Reaction Steps

(S)-6-(1-Hydroxy-3-(tritylthio)propan-2-yl)-1,3-dimethyl-5-phenyl-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (step 2) (2.5 g, 4.25 mmol) was dissolved in DCM (80 mL) and triethylamine (1.186 mL, 8.51 mmol) was added followed by methanesulfonyl chloride (0.398 mL, 5.10 mmol). The mixture was stirred at room temperature for 2 hours, further methanesulfonyl chloride was added and the mixture stirred for 50 mins. The reaction mixture was quenched with sat. NaHCO3(aq) and extracted with DCM. The organic phase was passed through a hydrophobic frit and evaporated under vacuum. Purification by chromatography on silica, eluting with 20-100% EtOAc in iso-hexane gave the title compound.
