Versuchsvorschrift

In a pressure tube reactor, (S)-4-(5-bromopyrimidin-2-yl)-2-((6-(1-methyl-1H-pyrazol-4-yl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-1-yl)methyl)morpholine (50 mg, 0.11 mmol) was added, and then 1M Na2CO3 (0.33 mL, 0.33 mmol) was added. Pd(PPh3)4 (6 mg, 0.005 mmol) was further added, and then 1,4-dioxane (1 mL) and 2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolane-2-yl)benzaldehyde (41 mg, 0.16 mmol) were added. The mixture was stirred at room temperature for 10 minutes under nitrogen gas, and then stirred at 105° C. for 13 hours. When the reaction was completed, the organic layer was extracted with ethyl acetate and water, and the extra water was removed by sodium sulfate, followed by concentration under reduced pressure. Solid was generated using ether and hexane, followed by filtration, to give (S)-2-fluoro-4-(2-(2-((6-(1-methyl-1H-pyrazol-4-yl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-1-yl)-methyl)morpholino)pyrimidin-5-yl)benzaldehyde (41 mg, 0.087 mmol) with a yield of 76%.
