실험 절차
In a 10 mL round-bottomed flask equipped with a condenser and a stirring bar was placed pyrazole (0.50 g, 7.3 mmol), acrylic acid (0.50 mL, 7.3 mmol) and triethylamine (3 mL). The reaction mixture was refluxed for 6 hours. After removing triethylamine, the viscous oil was dried on high vacuo during 12 hours to yield quantitatively the desired acid (1.0 g) suitable for the next step without further purification.
