Versuchsvorschrift

NaH as a 60% dispersion in mineral oil (31.63 mg, 0.7908 mmol) was added to a solution of benzyl alcohol (85.52 mg, 81.84 μL, 0.7908 mmol) in THF (4 mL). After stirring at ambient temperature for 5 minutes, 3,5-dibromopyrazin-2-amine (100 mg, 0.3954 mmol) was added and the mixture was stirred for 1 hour at ambient temperature then heated at 80° C. under microwave conditions for 15 minutes. The reaction mixture was cooled to ambient temperature, concentrated in vacuo and used directly in the next step without further purification.
