To a solution of 5-chloro-N2-(2,5-dimethyl-4-(piperidin-4-yl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine (30 mg, 0.073 mmol) in acetonitrile (1 mL) was added Cs2CO3 (47 mg, 0.15 mmol) and 4-iodotetrahydro-2H-thiopyran (48 mg, 0.22 mmol). This mixture was then stirred at 80° C. for 16 hr. After cooling down to room temperature, the mixture was treated with saturated aqueous NH4Cl solution (3 mL) and extracted with EtOAc (3×3 mL). The organic layers were combined and concentrated. The residue was purified by silica gel chromatography (Gradient 0˜8% MeOH/CH2Cl2 with NH3) to provide 5-chloro-N2-(2,5-dimethyl-4-(1-(tetrahydro-2H-thiopyran-4-yl)piperidin-4-yl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine as a white solid. ESMS m/z 512.2 (M+H+).
