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 (78 mg, 0.19 mmol) and TEA (0.52 mL, 3.78 mmol) in DCM (10 mL) was added 3-chloropropane-1-sulfonyl chloride (63 mg, 0.36 mmol, in 1 mL DCM). After stirring at rt for one hour, EtOAc (100 mL) was added. The mixture was sequentially washed with water (10 mL), brine (10 mL), dried over Na2SO4 and concentrated in vacuo. The crude product was purified by silica chromatography (0-100% EtOAc in hexanes gradient) to give 5-chloro-N2-(4-(1-(3-chloropropylsulfonyl)piperidin-4-yl)-2,5-dimethylphenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine as an off white solid; ESMS m/z 552.2 (M+H+).
