실험 절차
A mixture of 2-Cyanomethyl-4,6-dimethoxy-benzoic acid (1.75 g×3), 3-amino-5-methylpyrazole (1.5 g×3) in acetic acid (10 ml×3) were sealed in microwave process vial (20 ml×3). The mixture was heated at 140° C. for 30 minutes under microwave irradiation. The mixture was evaporated to oil, and the oil was dissolved in 1.5 ml MeOH. This solution was added dropwise to 50 ml water. After stirred for 1 hour, solid was collected and was purified by flash column chromatography to give product (6.07 g, 85%). LC-MS: m/e 301 (MH+).
