Procedure

To a solution of N-{5-[(9-chloro-6-oxo-6,7-dihydro-5H-pyrimido[5,4-d][1]benzazepin-2-yl)amino]pyridin-2-yl}-2,2-dimethylpropanamide (0.220 g, 0.38 mmol) in THF (3 mL) and MeOH (4 mL) at rt was added 6M HCl in water (5 mL). The solution was allowed to stir at 100° C. for 22 h. The organic solvents were allowed to boil off and the aqueous mixture was allowed to cool to rt. Solid K2CO3 was added and the mixture was filtered. The resulting solid was collected and purified by column chromatography to give 2-[(6-aminopyridin-3-yl)amino]-9-chloro-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (0.095 g, 71%).
