With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.39136-63-5,5-Phenylthiazol-2-amine,as a common compound, the synthetic route is as follows.
To 5-phenylthiazol-2-amine (0.52 g, 2.9 mmol) inacetonitrile (6 mL) was added 1,1′-thiocarbonyldiimidazole(0.68 g, 3.8 mmol). The reaction mixture was stirred at 65 C.for 2 hours. The precipitate was filtered and washed withacetonitrile (2×20 mL) to yield intermediate N-(5-phenylthiazol-2-yl)_1H-imidazole-I-carbothioamide. The intermediatewas taken up in N,N-dimethylformamide (30 mL) andtreated with (3-(aminomethyl)-3-hydroxy-I-ammoniobicyclo[2.2.2]octan-I-yl)trihydroborate (0.5 g, 2.9 mmol). Thereaction mixture was stirred for 5 hours at 65 C. The reactionwas concentrated in vacuo and purified via silica gel chromatography(30-100% ethyl acetate/hexane). The product fractionswere combined and concentrated in vacuo to yield(3-hydroxy-3-((3-(5-phenylthiazol-2-yI)thioureido)methy1)l-ammoniobicyclo[2.2.2]octan-I-yl)trihydroborate (0.85 g,2.19 mmol, 74.4% yield) as a white powder., 39136-63-5
As the paragraph descriping shows that 39136-63-5 is playing an increasingly important role.
