3-(1,3-Dimethyl-2,4-dioxo-6-(2-(tritylthio)ethyl)-2,3,4,6-tetrahydro-1H-pyrrolo[3,4-d]pyrimidin-5-yl)benzonitrile (step 1)(573 mg, 0.983 mmol) was dissolved in DCM (20 ml) to form a clear brown solution and passed through 2×500 mg Isolute® Si-TMT (silica bound equivalent of 2,4,6-trimercatotriazine) cartridges to afford a colourless solution. The solution was placed under a nitrogen atmosphere and whilst stirring rapidly, treated dropwise with triethylsilane (1.571 ml, 9.83 mmol) followed TFA (3.79 ml, 49.2 mmol). After stirring at RT for 1 h, the reaction mixture was concentrated under reduced pressure to yield a white solid. The isolated crude product was triturated with diethyl ether and dried in a vacuum oven at 50° C. to afford the title compound;
