Add palladium/carbon (2.2 g, 1.0 mmol, 5% on carbon) to a nitrogen purged solution of 7-azido-5-[2-(tert-butyl(dimethyl)silyl)oxyethyl]-7H-pyrido[2,3-d][3]benzazepin-6-one (39.8 g, 92.3 mmol) in ethanol (923 mL). Evacuate/fill with hydrogen three times and stir under hydrogen (one atmosphere) at ambient temperature overnight. Filter over Celite®, rinse with ethanol and ethyl acetate and concentrate to obtain the title compound as a transparent oil (36.6 g, 89.9 mmol, 97%). MS (m/z): 384 (M+1).
