Paragraph 0048-0053, (2020/03/09)
The invention discloses a method for preparing a 2-aminothiazole compound. The method comprises the following steps: in an organic solvent, carrying out a condensation reaction on thiourea representedby a formula (II) and a ketone compound represented by a formula (III) at 50-120 DEG C for 6-24 h under the catalysis of elemental iodine, and after the reaction is finished, carrying out post-treatment on the reaction solution to obtain the 2-aminothiazole compound represented by a formula (I). According to the invention, the method has characteristics of cheap and easily available reaction rawmaterials, mild reaction conditions, simpleness, no requirement of transition metal catalysts and a stoichiometric halogenating reagents and cost reducing, and can be used for synthesizing a series of2-aminothiazole derivatives, and the prepared products can be used as important intermediates for synthesizing thiazole structure-containing drugs or bioactive compounds.
