Procedure

To a mixture of thiomorpholine-1,1-dioxide (70 mg) and DMF (4 mL) were added [6-(4,4-dimethylcyclohexyl)-2-methylthieno[2,3-d]pyrimidin-4-yl]methyl methanesulfonate (120 mg) and TEA (150 μL), followed by stirring at room temperature overnight. To the reaction mixture was added water, followed by extraction with EtOAc. The organic layer was washed with brine, dried over MgSO4, and then concentrated under reduced pressure. The residue was purified by basic silica gel column (hexane/EtOAc) to obtain 6-(4,4-dimethylcyclohexyl)-4-[(1,1-dioxidothiomorpholin-4-yl)methyl]-2-methylthieno[2,3-d]pyrimidine (102 mg).
