반응 단계
2 g of 5-methyl-2-phenyl-2,4-dihydro-3-pyrazolone, 188 ml of trimethyl orthoformate and 1.29 ml of o-anisidine are heated with stirring in 5 ml of glacial acetic acid at 70° C. for 2 h. The reaction mixture is cooled and 10 ml of methanol are added. The precipitate which has separated out is filtered off with suction and recrystallized from ethyl acetate.
