Versuchsvorschrift

A solution of 262 mg (1.00 mmol) 5-chloro-3-(4-methoxy-phenyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and 183 mg (1.00 mmol) 4-amino-pyrazole-1-carboxylic acid tert-butyl ester in 2.5 ml 2-methoxy-ethanol is stirred for 3 hours at 100° C. The reaction mixture is cooled to room temperature and water is added. The resulting precipitate is filtered off, washed with water and dried. The crude product is recrystallized from isopropanol giving “A3” as brown crystals; HPLC/MS (A): 1.6 min, [M+H] 309;
