Procedure

600 mg of N-diaminomethylene-2-methyl-4-methoxy-5-methylsulfonylbenzamide (obtainable according to Ex. 2) are boiled for 3 hours in 80 ml of pyridine together with 1 g of pyridine hydrochloride. The mixture is cooled and evaporated, and the residue is worked up in the customary manner to give N-diaminomethylene-2-methyl-4-hydroxy-5-methylsulfonylbenzamide, m.p. >260°.
