Participants

Reaction Steps

To a solution of tert-butyl (6-((tert-butoxycarbonyl)(4-(hydroxymethyl)-2-nitrophenyl)amino)pyrimidin-4-yl)(methyl)carbamate (1.5 g, 3.488 mmol) in acetone (20 mL) under an argon atmosphere at 0° C., was added potassium carbonate (0.48 g, 6.97 mmol) followed by dimethyl sulfate (0.87 g, 6.97 mmol). The resulting reaction mixture was then refluxed for 24 h and then allowed to cool to rt. The reaction mixture was concentrated under vacuum to obtain a crude residue. The residue was purified by silica gel column chromatography to afford the title compound (0.3 g, yield: 19%) as a solid. MS (ESI): 490.55 [M+H]+.
