| titleOfInvention | Preparation method of thiabendazole |
| abstract | The present invention relates to a process for preparing thibendazole, wherein a condensation reaction of 1,2-phenylenediamine and 3-halopyruvic acid represented by the following Chemical Formula 1 under a reaction solvent and an acid catalyst is represented by Chemical Formula 2 below. Preparing an imidazole derivative; And the benzimidazole derivative prepared through the step of reacting the benzimidazole derivative with formamide represented by the following formula (3) in the presence of phosphorus penta sulfide, can be obtained in high yield, and does not use a polyacid, which is a conventional acid catalyst. By doing so, the problem of wastewater treatment can be solved.n n n n Formula 1n n n n n n n n n Wherein X is Cl or Br.n n n n Formula 2n n n n n n n n n Wherein X is Cl or Br.nn n n n Formula 3 |
