Dichloromethane (1 mL), N,N-diisopropylethylamine (0.087 mL, 0.50 mmol) and methanesulfonyl chloride (0.023 g, 0.20 mmol) were added to a vial containing N-(3-(1-(2-aminoethyl)-1H-pyrazol-4-yl)-5-methylphenyl)-4-(difluoromethyl)pyrimidin-2-amine hydrochloride (0.038 g, 0.10 mmol). The reaction mixture was stirred for two hours and then concentrated under reduced pressure. The residue was purified by reverse phase chromatography (acetonitrile/water with 0.1% TFA modifier) to afford N-(2-(4-(3-((4-(difluoromethyl)pyrimidin-2-yl)amino)-5-methylphenyl)-1H-pyrazol-1-yl)ethyl)methanesulfonamide.
