実験手順

Following a similar procedure to that described in example 1 method B, but using 3-amino-5-methyl-2H-pyrazole instead of 3-amino-2H-pyrazole and 1-phenyl-2-(4-pyridyl)vinyl benzoate (obtained in reference example 5) instead of 1-(4-fluorophenyl)-2-(4-pyridyl)vinyl 4-fluorobenzoate, the title compound was obtained in solid white form (yield: 16%).
