Versuchsvorschrift
To a solution of compound 2-azido 4′-bromoacetophenone (1.0 g, 4.17 mmol) in MeOH (20 mL), Pd/C (10%, 100 mg) was added to the solution. The mixture was degassed and stirred under hydrogen system for 4 hours. The mixture was filtered and evaporated in vacuo without further purification to obtain 2-amino 4′-bromoacetophenone (0.535 g, 2.499 mmol, 60% yield). 1H NMR (d-MeOH) 4.63 (d, J=4.8 Hz, 2H), 7.62 (d, J=7.2 Hz, 2H), 8.03 (d, J=7.2 Hz, 2H) ppm.
