Versuchsvorschrift
300 mg (1.08 mmol) of 6,8-dibromoimidazo[1,2-a]pyrazine were dissolved in 10 ml of DMSO, and 0.6 ml (4.3 mmol) of triethylamine and 360 mg (1.3 mmol) of 4-amino-2-[(2-aminoethyl)amino]-1,3-thiazole-5-carbonitrile dihydrochloride (Example 8A) were added. The mixture was heated at 140° C. in a microwave for 1 h. Purification by preparative HPLC gave 376 mg (83% of theory) of the product as a solid.
