| titleOfInvention | Novel intermediate of imidafenacin, method for producing the same, and method for producing imidafenacin using the same |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing imidafenacin of ultra high purity that can efficiently remove many side reaction substances generated during the reaction, can be synthesized economically in a large amount, and ensures suitable stability. . The present invention provides 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutyronitrile benzene sulfonate or oxalate which is preferably used in a method for producing imidafenacin. Using the 4- (2-methyl-1-imidazolyl) -2,2-diphenylbutyronitrile benzene sulfonate or oxalate of the present invention, the total flexible material is 0.10% or less of the total, preferably Ultra high purity imidafenacin of 0.05% or less, more preferably 0.02% or less can be produced in high yield. |
