| abstract | PROBLEM TO BE SOLVED: To provide a 2-substituted-3- (biphenyl-4-yl) methyl-7-methyl-3H-imidazo [important as a pharmaceutical intermediate such as an angiotensin II receptor antagonist] 4,5- b] A novel precursor compound of a pyridine derivative and a method for producing the same are provided. SOLUTION: A 2-substituted-3- (biphenyl-4-yl) methyl-7-methyl-3H-imidazo [4,5-b] pyridine-N-oxide derivative represented by the following formula (I): A method for producing the above compound, wherein [(N-biphenyl-4-yl) methyl] alkylamido-4-methyl-3-nitropyridine derivative is reduced, dehalogenated and cyclized in the presence of a solvent. [Wherein, R 1 is a hydrogen atom or a halogen atom, R 2 is a hydrogen atom or a methyl group, R 3 is a cycloalkyl group, a lower alkyl group, or the like, and R 4 is a cyano group, a group represented by —COOR 5 , or the like. Show. |
