Reaction Steps
The title compound is synthesized according to general procedure GP2 starting from 1.5 g (5.7 mmol) 4-chloro-5-iodo-6-methyl-pyrimidin-2-ylamine (GP3) and 1.7 g (15 mmol) 2-amino-5-ethynyl-pyridine (GP15) using 106 mg (0.56 mmol) CuI, 390 mg (0.56 mmol) PdCl2(PPh3)2 and 8 mL (55 mmol) triethylamine in 12 mL dry DMF. For the work-up water is added to the reaction mixture. The precipitate is collected, dried at 40° C. and re-crystallized from MeOH. Yield: 1.5 g (83%, approximately 80% pure).
