Procedure

To a solution of 2-{[5-(3-hydroxypropyl)-2-methylpyridin-3-yl]amino}-9-(trifluoromethyl)-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (0.25 g, 0.564 mmol) in THF (10 ml) were added imidazole (0.077 g, 1.13 mmol) and tert-butyldimethylsilyl chloride (0.10 g, 0.676 mmol). The reaction mixture was allowed to stir overnight at rt and was then concentrated. Water (10 ml) and saturated NaHCO3 (10 ml) were added. The resulting mixture was allowed to stir for 1 h at rt. The mixture was extracted with EtOAc (2×30 mL). The organic solutions were combined, dried over Na2SO4, filtered and concentrated. The residue was purified by column chromatography to give 2-{[5-(3-{[tert-butyl(dimethyl)silyl]oxy}propyl)-2-methylpyridin-3-yl]amino}-9-(trifluoromethyl)-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (0.16 g, 0.29 mmol, 51%).
