10-[2-(Dimethylamino)propyl]-10H-phenothiazine - Production method
Add phenthidine and base to toluene, and heat and reflux for 1h. Slightly cold, add 2-chloro-1-dimethylaminopropane toluene solution, reflux with water for 10-12h. Cold to below 50 ℃, the reaction liquid is filtered, the filter residue is washed with a small amount of acetone and water, the washing filtrate is combined, standing, toluene layer is separated, toluene is recovered by distillation under reduced pressure, and 220-260 ℃(1.33-2.66kPa) fraction is collected to obtain promethazine (base). The promethazine base is added to acetone, and dry hydrogen chloride gas is introduced at about 50 ℃ for salt formation reaction to generate promethazine hydrochloride.
