Abstract

1. A process for the preparation of amezinium metilsulfate by reacting 1-phenyl-4-aminopyridaz-6-one with dimethyl sulfate and subsequently isolating the amezinium metilsulfate by crystallization, wherein unreacted dimethyl sulfate, before crystallization of the amezinium metilsulfate, is bonded to an amide of the formula R**1 -(NH)n -CO-NR**2 R**3 , where R**1 is hydrogen, C1 -C8 -alkyl, C1 -C6 -alkoxy or C1 -C8 -alkylamino, R**2 and R**3 are each hydrogen or C1 -C8 -alkyl, or R**1 and R**2 together are a C3 -C5 -alkylene radical, and n is 0 or 1, at least one of the radicals R**1 , R**2 and R**3 , however, denoting hydrogen, or to the corresponding thioamide.
