Synthesis method

By2-Chlorophenothiazine[92-39-7]Condensation and salt formation. 1.Condensation in reaction Add 2- Chlorophenothiazine and toluene, then add sodium hydroxide, stir and heat to reflux, remove moisture, and in 110℃ dripping1-Chlorine-3-Toluene solution of dimethylaminopropane, the reactant is decompressed to recover toluene to obtain chlorpromazine,C17H19CIN2S,[50-53-3]. 2.Salt Stir and heat chlorpromazine and isopropyl alcohol until 40℃, access dry hydrogen chloride to pH 4-5, and the chlorpromazine hydrochloride is obtained as a salt.


has central stabilizing, antiemetic, anticonvulsant, anti- Adrenaline and other effects. Used to treat schizophrenia and mania. Anxiety disorders, mental disorders, nausea, vomiting, etc. It can also be used for artificial hibernation and low-temperature anesthesia.
