To a 4M solution of HCl in dioxane (20 mL) was added tert-butyl[3-(6-methyl-5-{[6-oxo-9-(trifluoromethyl)-6,7-dihydro-5H-pyrimido[5,4-d][1]benzazepin-2-yl]amino}pyridin-3-yl)propyl]carbamate (1.10 g, 2.04 mmol). The reaction mixture was allowed to stir at rt overnight and then concentrated to give 2-{[5-(3-aminopropyl)-2-methylpyridin-3-yl]amino}-9-(trifluoromethyl)-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (1.35 g, 2.30 mmol, >99%) as a brown solid. LCMS (FA): Rt=0.55 min, m/z=443.0 (M+H).
