Reaction Steps
To the solution of 2,4-dichloro-6-methylpyrimidine (1.63 g) and 3-cyclopropyl-1H-pyrazol-5-amine (1.24 g) in DMF (20 ml) was added NaI (1.49 g) and DIEA (1.72 ml). And the mixture was stirred at 80° C. overnight. The mixture was concentrated to remove DMF. The residue was suspended into EtOAc. The insoluble material was filtered off and washed with EtOAc. The filtrate was concentrated and the residue was pufiried with silica gel column chromatography (eluent: CHCl3/MeOH=98/2˜90/10) to give 2-chloro-N-(3-cyclopropyl-1H-pyrazol-5-yl)-6-methylpyrimidin-4-amine (1054 mg) as a pale pink solid.
