METHOD FOR PREPARING TRITYL CANDESARTAN

The present invention uses a candesartan cyclic compound as a starting material and performs thereon a three-step reaction of forming tetrazole, hydrolysis and adding a protecting group to directly obtain trityl candesartan without separating an intermediate product via crystallization. The operating process is simple and thus is more applicable to industrial production.

METHOD FOR OBTAINING BENZIMIDAZOLE DERIVATIVES AND INTERMEDIATES THEREOF

The present invention relates to a method for obtaining benzimizadole derivatives and intermediates thereof, preferably, for obtaining Candesartan and Candesartan cilexetil. Said method allows the benzimizadole derivatives to be obtained with a higher yield.
