Reaction Conditions

Reaction Steps

2-Chloro-5-nitrobenzophenone (1.3 g,5.0 mmol), tin(II) chloride (4.5 g, 20 mmol), and ethanol (20 ml) were mixed and heated at 70° C. for 1 h. After cooling to room temperature, to the reaction mixture were added ice, EtOAc and aqueous NaHCO3 and it was stirred for 30 min. The organic layer was washed with brine and dried over MgSO4. Filtration and evaporation afforded 5-amino-2-Chlorobenzophenone. 1H NMR, 7.85(m,2H), 7.30-7.66 (m,3H7.20 (d,1H,J=8.8 Hz), 6.60-6.80 (m,2H). MS calcd 231.1; MS (M+1) 232.0.
