Versuchsvorschrift

To a vigorously stirring suspension of 2 g (7.4 mmol) of 5-bromo-6-chloro-2-(methylsulfinyl)pyrimidine-4-amine (intermediate 3) in 40 ml of DMF, 0.87 g (7.4 mmol) indazole and 1.4 g (4.4 mmol) of cesium carbonate were added. The reaction mixture was stirred at room temperature for 20 minutes. The solution was poured onto 200 ml of ice-water. The resulting precipitate was filtered, washed with cold water and dried. The desired product is obtained as a white solid 1.31 g (54.6%)
