Reaction Steps

To a solution of (3-bromo-5-methylpyridin-2-yl)-(1-pyridin-4-ylethylidene)amine (4.25 g, 14.65 mmol) in dimethylformamide (75 ml) was added DABCO® (4.93 g, 43.96 mmol) and ], bis-dichlorotriphenylphosphine palladium (0.52 g, 0.73 mmol). The reaction mixture was heated at 120° C. under argon atmosphere. After 1.5 days, the reaction mixture was cooled into room temperature and poured into 10% hydrochloric acid (100 ml). The solution was filtered through Celite® and the filtrate was neutralized to pH 7 with 10% sodium hydroxide and the solid was filtered off to give 4-methyl-2-(pyridin-4-yl)-1H-pyrrolo[2,3-b]pyridine (1.57 g) as a brown solid.
