Procedure

To a stirred suspension of 3-[7-(4-fluoro-phenyl)-4-oxo-4,5-dihydro-3H-benzo[b][1,4]diazepin-2-yl]-benzonitrile (Example 57) (355 mg, 1 mmol) in EtOH (60 mL) was added at 23° C. over 6 h 50% aqueous hydroxylamine solution (3.48 mL, 60 mmol) in 6 portions. The mixture was cooled in the ice-bath, diluted with H2O (100 mL) and stirred for 1 h. The precipitate was collected by filtration, washed with water and Et2O, and triturated with ethyl acetate to give the title compound as light yellow solid (336 mg).
