Procedure

6-(2-Ethylaminopyrimidin-4-yl)-3-oxo-2,3-dihydropyridazine-4-carboxylic acid (2amino-4-chlorophenyl)amide (50 mg) are stirred in 1 ml of glacial acetic acid at 100° C. for 3 hours. After cooling, the precipitate is filtered off with suction, stirred with aqueous sodium bicarbonate solution and again filtered off with suction, washed with water and dried in vacuo.
