Abstract: The present disclosure provides, for example, a method for producing 2-(4-cyclopropyl-2-fluoroanilino)-3,4-difluoro-5-[[3-fluoro-2-(methylsulfamoylamino)pyridin-4-yl]methyl]benzamide or a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable solvate of the compound or salt, the method comprising reacting (2-amino-3-fluoropyridin-4-yl)methanol with methyl chloroformate and N,N-dimethylaminopyridine in acetonitrile to give (2-amino-3-fluoropyridin-4-yl)methyl methyl carbonate. According to the present disclosure, there is provided a method for producing a specific aryl amide derivative that has RAF/MEK complex-stabilizing activity and/or MEK-inhibiting activity and is useful for the treatment or prevention of a cell proliferative disorder, particularly a cancer, the method enabling the aryl amide derivative to be produced with a small number of steps.
