실험 절차

To a solution of 5-tert-butyl-1-(4-fluorophenyl)pyrazol-4-amine (0.03 g, 0.13 mmol) in DMF (1.0 mL) was added 2-[2-methyl-4-(trifluoromethyl)imidazol-1-yl]propanoic acid (0.029 g, 0.13 mmol), followed by diisopropylethylamine (0.033 g, 0.26 mmol) and HATU (0.054 g, 0.14 mmol). After stirring at room temperature for 1 h, the reaction was diluted with water and the aqueous layer was extracted with ethyl acetate (2×5 mL). The combined organic layers were washed with brine, dried (Na2SO4), filtered, and concentrated in vacuo. The resulting crude product was purified by reverse phase HPLC (C18 column, acetonitrile-H2O with 0.1% TFA as eluent) to give the title compound as a white solid (0.0145 g, 0.034 mmol, 25%). 1H NMR (400 MHz, CDCl3) δ 7.77 (s, 1H), 7.45 (q, J=1.2 Hz, 1H), 7.33-7.24 (m, 2H), 7.16-7.07 (m, 2H), 6.89 (s, 1H), 4.90 (d, J=7.3 Hz, 1H), 2.47 (s, 3H), 1.86 (d, J=7.3 Hz, 3H), 1.11-1.03 (m, 9H); MS: (ES) m/z calculated for C21H23F4N5O [M+H]+ 438.2, found 438.0.
