Synthesis method

By2-Chlorophenothiazine[92-39-7]Condensation and salt formation.1.Condensation in the reaction pot2-Chlorophenothiazine and toluene, then add sodium hydroxide, stir and heat to reflux, remove moisture, and in110drop1-Chlorine-3-Dimethylamine A toluene solution of propane is used, and the reactant is decompressed to recover toluene to obtain chlorpromazine,C17H19CIN2S,[50-53- 3]. 2. Salt Stir and heat chlorpromazine and isopropyl alcohol until40, add dry hydrogen chloride topH4-5, to obtain chlorpromazine hydrochloride as a salt.


Representative drugs among phenothiazines. It has a stabilizing effect on the central nervous system in small doses, and has an antipsychotic effect when used continuously in large doses. This product inhibits the subthalamic thermoregulatory center, causing the body temperature to rise and fall with the ambient temperature. It can be used with other drugs to reduce the body temperature to below normal body temperature, and improves metabolism. Reducing is called artificial hibernation. Mainly used for antipsychotics, enhancing the effects of hypnotics, anesthetics, analgesics and anticonvulsants. It can also be used to relieve vomiting and intractable hiccups and induce artificial hibernation.
