Reaktionsschritte

200 mg of palladium on charcoal (10% palladium) are added to a solution containing 0.5 g (1.77 mmol) of 6-bromo-8-morpholinoimidazo[1,2-a]pyrazine for 120 ml of anhydrous methanol and 2 g of potassium hydroxide. The mixture is hydrogenated at atmospheric pressure for 12 hours. The solution is filtered, concentrated and taken up with water; after extraction with dichloromethane and evaporation of the solvent, 0.34 g (92%) of 8-morpholinoimidazo[1,2-a]pyrazine (m.p. 127° C.) is obtained.
