In a article，once mentioned of 25983-13-5
The invention discloses an important cephalosporin antibiotics lorraine ester intermediate 4 – (the 4 […] -pyridyl) – 1,3-thiazole-2-thiol synthesis method, the isonicotinic acid ethyl ester in alkaline condition, and the acetic acid ethyl ester claessen (claisen) condensation reaction, then the acidic hydrolysis decarboxylative, and after the bromination reaction of bromine with dithio amino a acid ammonium Guan Huan, the final reflux in glacial acetic acid, to obtain the corresponding 4 – (the 4 […] -pyridyl) – 1,3-thiazole-2-thiol. There are few synthesis steps of the present invention, low cost, the material used is cheap and easy to obtain, is beneficial for the industrial production, pollution is small.
