Reaction Steps
A solution of 110 mg of 6-(2-ethylaminopyrimidin-4-yl)-3-oxo-2,3-dihydropyridazine-4-carboxylic acid, 2 ml of DMF and 0.17 ml of triethylamine is mixed with 192 mg of Hatu and stirred at room temperature for 30 minutes. Then 66 mg of 4-chloro-phenylenediamine are added, and the mixture is stirred at room temperature overnight. 5 ml of water are added to the mixture, and the precipitate is briefly stirred and then filtered off with suction and dried.
