Product Description

Mizolastine intermediate 4 CAS number is 84946-20-3, full chemical name of 1-(4-Fluorobenzyl)-2-chlorobenzimidazole, it is the key intermediate for the preparation of mizolastine, there are two traditional synthetic routes.Firstly,use o-phenylenediamine as raw material, adding dilute hydrochloric acid to react to get o-benzene Diammonium monohydrochloride, then mixed with urea, fused and condensed at high temperature to obtain 2-hydroxybenzimidazole, and then add 4-fluorobenzyl chloride to process N-dealkylation, obtain 1- (4-fluorobenzyl) -1 , 3-dihydro-2H-benzimidazol-2-one, and then use chlorinated phosphorus oxychloride to give the desired product. Second, the process from the starting material to the second step, 2-hydroxybenzimidazole, is exactly the same as the first route, except that this route, after obtaining 2-hydroxybenzimidazole, Phosphorus reaction to give 2-chlorobenzimidazole, N-alkylation with 4-fluorobenzyl chloride to give the target compound Mizolastine Intermediate 4 CAS number 84946-20-3..
