reported compound, 1-methyl-5-(trifluoromethyl)-2,3,4,5-tetrahydropyrazol-3-one, 4, a series of regional isomers of 1-methyl-5-(trifluoromethyl)-3-chloropyrazole, newly substituted in the 4-position were prepared by original syntheses. Chief among them was the new regional 4-hydroxy isomer, 3a, a linkage reagent valuable for preparing new SAR candidates in the bio-active pyrazole phenyl ether series
利用最近报道的化合物1-methyl-5-(trifluoromethyl)-2,3,4,5-tetrahydropyrazol-3-one,4,是1-methyl-5-(trifluoromethyl)-3-的一系列区域异构体通过原始合成制备在4-位新取代的氯吡唑。其中最主要的是新型的区域4-羟基异构体3a,一种对制备具有生物活性的吡唑苯基醚系列新的SAR候选物有价值的连接剂。
