Procedure
To a solution of (4Z)-4-[(dimethylamino)methylene]-8-(trifluoromethyl)-3,4-dihydro-1H-1-benzazepine-2,5-dione (1.05 g, 3.51 mmol) and tert-butyl[3-(5-{[amino(imino)methyl]amino}-6-methylpyridin-3-yl)propyl]carbamate (1.62 g, 5.27 mmol) in EtOH (50 mL) was added potassium carbonate (2.91 g, 21.1 mmol). The reaction mixture was allowed to stir at 80° C. overnight. The reaction mixture was diluted with water (100 mL) and EtOAc (50 mL). The organic solution was separated and the aqueous solution was extracted with EtOAc (2×50 mL). The organic solutions were combined, washed with brine (100 mL), dried over MgSO4, filtered and concentrated to give 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 (2.13 g, >99%) as a dark brown solid. LCMS (FA): Rt=1.79 min, m/z=543.0 (M+H).
