실험 절차
A microwave vial equipped with a magnetic stirrer was charged with the mixture of 1%5-dimethyl-1′H-1,4′-bipyrazol-4-amine and 1′,3-dimethyl-1′H-1,4′-bipyrazol-4-amine (50 mg, 0.28 mmol), 2-chloro-N-methyl-5-(trifluoromethyl)pyrimidin-4-amine (60 mg, 0.28 mmol), and t-BuOH (3 mL). The mixture was heated at 100° C. under microwave irradiation for 1 h. After removal of the volatiles, the residue was purified by prep-HPLC to afford N2-(1′,5-dimethyl-1′H-1,4′-bipyrazol-4-yl)-N4-methyl-5-(trifluoromethyl)pyrimidine-2,4-diamine (17 mg, 17%) as a white solid and N2-(1′,3-dimethyl-1′H-1,4′-bipyrazol-4-yl)-N4-methyl-5-(trifluoromethyl)pyrimidine-2,4-diamine (26 mg, 26%) as a white solid.
