To a mixture of [6-(4,4-dimethylcyclohexyl)-2-methylthieno[2,3-d]pyrimidin-4-yl]methyl methanesulfonate (200 mg), DIPEA (139 μL), and DMF (3.0 mL) was added tetrahydro-2H-thiopyran-4-amine-1,1-dioxide (97 mg), followed by stirring at room temperature for 4 hours. To the reaction mixture was added a saturated aqueous NH4Cl solution, followed by extraction with EtOAc. The organic layer was washed sequentially with water and brine, dried over MgSO4, and then concentrated under reduced pressure. The residue was purified by silica gel column and dissolved in EtOAc, and 4 M HCl/EtOAc (137 μL) was added dropwise. The precipitate was collected by filtration and then dried to obtain N-{[6-(4,4-dimethylcyclohexyl)-2-methylthieno[2,3-d]pyrimidin-4-yl]methyl}tetrahydro-2H-thiopyran-4-amine-1,1-dioxide hydrochloride (165 mg).
