Reaction Steps

To (4E)-8-chloro-4-[(dimethylamino)methylene]-3,4-dihydro-1H-1-benzazepine-2,5-dione (3.25 g. 12.3 mmol) in EtOH (50 mL) were added N-{2-methyl-6-[(1-methylpiperidin-4-yl)amino]pyridin-3-yl}guanidine *xHCl (6.5 g, 14 mmol) and potassium carbonate (13.6 g, 98.3 mmol). The reaction mixture was allowed to stir for 2 days at 70° C. and then allowed to cool to room temperature. The solids were filtered and the filtrate was concentrated to give a thick red oil. Water was added to the residue and the aqueous solution was extracted with EtOAc. The organic solutions were combined, dried, filtered and concentrated to give 9-chloro-2-({2-methyl-6-[(1-methylpiperidin-4-yl)amino]pyridin-3-yl}amino)-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (5,3 g, 93%).
