The potassium salt suspension of the anion of 4-amino-3,5-dichloropyridine in DMF (2-25 equivalents) Is introduced into a reaction vessel. A solution of 3-cyclopropylmethoxy-4-difluoromethoxybenzoyl chloride (1 equivalent) in DMF is slowly added to this suspension while stirring vigorously at a temperature of 15 to 40° C., preferably 20 to 30° C. After the reaction is complete, water is slowly added while stirring at 15-25° C., and the pH is adjusted to 2-3 with hydrochloric acid.
