실험 절차
A solution of 2-bromo-1-(5-methyl-1-phenyl-1H-pyrazol-4-yl)-ethanone (829 mg; 2.97 mmol) and 3-amino-4-methyl benzoic acid methyl ester in 6 mL of EtOH was stirred at 75° C., for 6 h. The mixture was cooled, and the resulting precipitate was filtered and washed with cold EtOH to provide 564 mg (1.55 mmol; 52%) of 4-methyl-3-[2-(5-methyl-1-phenyl-1H-pyrazol-4-yl)-2-oxo-ethylamino]-benzoic acid methyl ester as a white powder.
