A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 154212-60-9, Name is 2-Isopropyl-4-(methylaminomethyl)thiazole, molecular formula is C8H14N2S. In a Patent£¬once mentioned of 154212-60-9, Quality Control of: 2-Isopropyl-4-(methylaminomethyl)thiazole
The invention belongs to the field of medical intermediate synthesis, relates to ritonavir intermediate synthesis preparation method, and in particular relates to 2 – isopropyl – 4 – (methyl amino methyl) thiazole hydrochloride preparation method, the first reaction with thionyl chloride isobutyric acid, then ammonium sulfide and ammonia thio and ammoniation reaction, replace the existing technical first acylated, five after vulcanization phosphorus and sulfur on behalf of the reaction, to avoid large produced in the preparation process of the odor, pollution to the environment; this invention adopts the 1, 3 – dihydroxy acetone replaces the expensive, relatively large smell, high pollution of the 1, 3 – dichloroacetone, cost saving, environmental protection; preparation method of this invention the process is simple, the yield is higher than the existing technology, is suitable for industrial production.
