    • A method for preparing a novel imidazole derivative is provided to obtain the imidazole derivative useful as an important intermediate of a losartan derivative used for selectively synthesizing losartan with high yield. And a novel method for preparing the losartan using the imidazole derivative is provided. A method for preparing a compound represented by the formula(2) comprises the steps of: (a) chloroformylating a compound represented by the formula(4) in the presence of a chlorinating agent and a formylating agent to form a compound represented by the formula(3); and (b) reducing an aldehyde group of the compound of the formula(3) into an alcohol. The method for preparing a compound represented by the formula(1) comprises the steps of: (a) performing a [3+2] ring-addition reaction on the compound of the formula(2) with an azide-containing dieneophile in the presence of an anion activating agent to form a compound represented by the formula(1-1); and (b) treating the compound of the formula(1-1) with potassium hydroxide.
