反応手順
To 4-bromo-1,3-dimethyl-1H-pyrazole-5-carboxylic acid (0.3 g, 1.370 mmol) in DMF (5 mL) were added ammonium chloride (0.293 g, 5.48 mmol), HOBt (0.222 g, 1.644 mmol), and EDC (0.368 g, 1.917 mmol), followed by N-ethyl-N-isopropylpropan-2-amine (1.193 mL, 6.85 mmol). The reaction mixture was stirred for 18 hours at room temperature. The reaction mixture was subsequently diluted with EtOAc, washed with brine, dried over Na2SO4, and concentrated to give the title compound, which was used without further purification (0.28 g).
