overview
The chemical formula of bukrizine compound is 1-(p-tert-butylbenzyl)-4-(p-chlorobenzyl) piperazine, which is clinically used as a piperazine antihistamine, The antihistamine effect is stronger and longer than diphenhydramine, the antiemetic effect is also significantly longer, and it has a stable and anti-anxiety effect.
Indications
bukrizine is used for acute or chronic urticaria, eczema, dermatitis and other allergic skin diseases. It can also be used for motion sickness, insomnia, anxiety, etc.
Production method
Using tert-butanol as a raw material, in the presence of aluminum trichloride, it reacts with benzene to form tert-butadiene benzene, and uses paraformaldehyde, hydrochloric acid, etc. for chloromethylation reaction to form p-tert-butylbenzyl chloride, and then Condensation with piperazine to form p-tert-butylbenzylpiperazine hydrochloride, neutralize with alkali to obtain p-tert-butylbenzylpiperazine, and condensation with p-chlorodiphenylbromomethane to form chlorphenazine. Chlorbenzine hydrochloride is generated.
