Reaction of 1,1,4,4-tetrachloro-3-buten-2-one with 3,5-dimethylpyrazole gave 1,1-dichloro- 4,4-bis-(3,5-dimethyl-1-pyrazolyl)-3-buten-2-one. Treatment of the latter with amines resulted in replacement of one pyrazole ring by the amine residue with formation of the corresponding 4-amino-1,1-dichloro-4-(3,5- dimethyl-1-pyrazolyl)-3-buten-2-ones.
1,1,4,4-四氯-3-丁烯-2-酮与3,5-二甲基吡唑反应得到1,1-二氯-4,4-双-(3,5-二甲基-1-吡唑基)- 3-丁烯-2-一。后者用胺处理导致一个吡唑环被胺残基取代,形成相应的4-氨基-1,1-二氯-4-(3,5-二甲基-1-吡唑基)-3-丁烯- 2个。
