Reaction Steps

800 mg (1.66 mmol) of 1-[3-(5-bromopyrimidin-2-yl)benzyl]-6-(1-methyl-1H-pyrazol-4-yl)-1H-1,2,3-triazolo[4,5-b]pyrazine is suspended in 10 ml of THF and 1 ml of DMF, and 515 mg (1.99 mmol) of bis(pinacolato)diboron and 488 mg (4.97 mmol) of potassium acetate are added. The reaction mixture is evacuated and flushed with argon a number of times. 16.3 mg (0.023 mmol) of bis(triphenylphosphine)palladium(II) chloride is added, and the mixture is again evacuated and flushed with argon. The reaction mixture is stirred at 80° C. for 24 h. When the reaction of the starting material is complete, 255 mg (1.656 mmol) of sodium perborate trihydrate and 2 ml of water are added to the reaction mixture, which is then stirred at room temperature for 24 h. The reaction mixture is filtered off with suction and washed with ethyl acetate. The filtrate is subsequently adjusted to pH 12 using NaOH solution and extracted with ethyl acetate. The aqueous phase is neutralised using hydrochloric acid and extracted twice with ethyl acetate. The combined organic phases are then dried over sodium sulfate and evaporated under reduced pressure.
