Reaction Steps

10 ml of ethanol saturated with hydrochloric acid are added, with stirring, to a solution of the inert salt of 1-[(4-chloro-3-sulfamylbenzoyl)-amino]-2,4,6-triphenylpyridinium hydroxide (5.4 g, 0.01 mol) in ethanol (25 ml). After half an hour's stirring, the precipitate formed is filtered off, giving 5.2 g (90%) of 1-[(4-chloro-3-sulfamylbenzoyl)-amino]-2,4,6-triphenylpyridinium chloride of the formula ##STR16##
