To a mixture of 6-(4,4-dimethylcyclohexyl)-2-methylthieno[2,3-d]pyrimidine-4-carboxylic acid (150 mg), 4-methylpiperidin-4-ol (68 mg), HATU (262 mg), and NMP (2.1 mL) was added DIPEA (244 μL), followed by stirring at room temperature overnight. 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. The obtained purified product was suspended in IPE, collected by filtration, and then dried under reduced pressure to obtain [6-(4,4-dimethylcyclohexyl)-2-methylthieno[2,3-d]pyrimidin-4-yl](4-hydroxy-4-methylpiperidin-1-yl)methanone (120 mg).
