Paragraph 0036-0038, (2018/04/01)
The invention belongs to the field of medical intermediate synthesis, relates to a preparation method for ritonavir intermediate synthesis and particularly relates to a preparation method for 2-isopropyl-4-(methyl aminomethyl) thiazole hydrochloride. Isobutyric acid firstly reacts with thionyl chloride, and then ammonium sulfide and ammonium hydroxide are subjected to sulfo-reaction and aminating reaction, the existing process of using phosphorus pentasulfide for performing sulfo-reaction after acylation is replaced, the heavy smell is prevented from generating in the preparation process to avoid the environmental pollution. According to the invention, 1,3-dihydroxy acetone is adopted for replacing 1,3-dichloroacetone with high price, heavy smell and high pollution, the cost is saved and the preparation is environmentally friendly. According to the preparation method provided by the invention, the process is simple, the yield higher than that of the prior art and the preparation method is suitable for industrial production.
