Reaction Conditions

Temperature140 °C

Reaction Steps

8 g (28.9 mmol) of 6,8-dibromoimidazo[1,2-a]pyrazine were dissolved in 80 ml of DMSO, and 16.1 ml (115.6 mmol) of triethylamine and 5.154 g (31.78 mmol) of 6-[(2-aminoethyl)-amino]pyridine-3-carbonitrile (Example 2A) were added. The mixture was heated at 140° C. in a microwave for 1.5 h. The solution was poured into water and the precipitate was filtered off. Washing with water and drying under high vacuum gave 10.3 g (94% of theory) of the product as a solid.
