Versuchsvorschrift

An amount of 2.83 gm of 2-(2'-dimethylamino-4'-nitrophenyl)-imidazo[4,5-b]pyridine was hydrogenated in a mixture of 100 ml of methanol, 10 ml of concentrated methanolic hydrochloric acid, and 1 gm of palladium/charcoal for 4.5 hours at ambient temperature with hydrogen gas at 5 bar. The catalyst was then removed by filtration, the filtrate was concentrated by evaporation, and the residue was triturated with acetone to form crystals, filtered, and then washed with a mixture of ether and acetone.
