2.0 g (9.62 mmol) of 5-bromo-2-chloro-4-hydroxypyrimidine and 1.686 g (9.62 mmol) of 5-amino-pyridine-2-sulfonic acid amide are mixed in 50 ml of DMF (p.a.) with 2.88 ml of hydrochloric acid (4 molar in dioxane). It is stirred for 30 hours at 100° C., cooled and concentrated by evaporation. After being taken up in methanol, 1.505 g (45% of theory) of 5-(5-bromo-4-hydroxy-pyrimidin-2-ylamino)-pyridine-2-sulfonic acid amide is crystallized out, which is dried at 50° C. in a vacuum.
