実験手順

To a mixture of 2-fluoro-4-(4-methylpiperazin-1-yl)-5-(trifluoromethyl)aniline (37 mg, 0.133 mmol) and 2,5-dichloro-N-(5-methyl-1H-pyrazol-3-yl)pyrimidin-4-amine (36 mg, 0.147 mmol) in iPrOH (1 mL) was added HCl (100 uL, 4N in dioxane). The reaction vessel was then sealed and heated to 130° C. for 4 hr. After cooling to room temperature, the mixture was treated with saturated NaHCO3 aqueous solution (5 mL) and extracted with EtOAc (3×5 mL). The organic layers were combined and concentrated. The residue was purified by preparative thin layer chromatography (silica gel, 8% MeOH/CH2Cl2), to provide 5-chloro-N2-(2-fluoro-4-(4-methylpiperazin-1-yl)-5-(trifluoromethyl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine. ESMS m/z 485.2 (M+H+).
