Reaction Conditions:
in methanol; for 6 h;Reflux;
Steps:
2
To three reaction bottles were added 10.8 g (100 mmol) of phenylhydrazine, 11.6 g (100 mmol) of methyl methacrylate,100 mL of methanol. The temperature of the reaction mixture was raised to reflux for about 6 hours. The reaction liquid was quantified by liquid chromatography, and 1-phenyl-5-hydroxypyrazoleYield 85.7%.
