CAS 16595-80-5 Levamisole Hydrochloride for Medicinal Chemicals
Levamisole hydrochloride was prepared from racemic tetraimidazole by splitting, alkali analysis and acidification into salt.
Dibenzoyl-D-tartaric acid is boiled in water for 40min, hydrolyzed and neutralized with sodium hydroxide solution to pH 7.5, and then dded to racemic tetraimidazole. The levamisole is precipitated by generating salt with bisbenzoyl-tartaric acid. After separation, add sodium hydroxide solution to PH=9 and decompose levamisole. Then dissolved in dilute hydrochloric acid solution, after decolorization by activated carbon, the filtrate was concentrated nearly dry, and crystallized by adding acetone and cooling to 0℃. Filtered and dried to obtain levamisole hydrochloride.
