Reaction Steps
To a solution of N-{2-[(2,3-difluorobenzyl)thio]-6-[(1R)-1-methyl-2-(trityloxy)ethoxy]pyrimidin-4-yl}-4-methylpiperazine-1-sulfonamide (the product from step (100 mg) in DCM (3 ml) was added TFA (3 ml) dropwise. The reaction was then allowed to stir at room temperature for the following 3 h until complete. The reaction was then reduced in vacuo and the resulting residue was purified by preparative HPLC to yield the title compound as a white solid. Yield: 45 mg
