실험 절차
To a solution of (3-bromo-imidazo[1,2-a]pyrazin-8-yl)-methyl-amine (Example 1) (2.4 g, 11.9 mmol) in methanol (160 ml) was added Pd-C (10% wt. 0.1 eq). The mixture was hydrogenated at rt overnight, filtered, and washed with hot methanol. The organics were combined and concentrated to afford 2.8 g of crude imidazo[1,2-a]pyrazin-8-yl-methyl-amine (M).
