Participants

Reaction Steps

20 ml of ethanol saturated with hydrochloric acid are added, with stirring, to a suspension of the inert salt of 1-{[4-chloro-2-(2-furylmethylamino)-5-sulfamylbenzoyl]-amino}-2,4,6-trimethylpyridinium hydroxide (4.6 g, 0.01 mol) in ethanol (40 ml). After a few seconds, a transparent solution is obtained, which immediately starts to precipitate. The precipitate is filtered off and washed with ethanol, giving 4.9 g (98%) of 1-{[4-chloro-2-(2-furylmethylamino)-5-sulphamylbenzoyl]-amino}-2,4,6-trimethylpyridinium chloride hydrochloride of the formula ##STR15##
