To a mixture of N-(4-bromo-3-nitrophenyl)-3-(2-cyanopropan-2-yl)benzamide 61 (400 mg, 1.030 mmol) and ZINC (1.011 g, 15.46 mmol) in THF (10 mL) at −5° C., acetic acid (1.180 mL, 20.61 mmol) was added. The reaction mixture was stirred at −5° C. for 30 min and 1 h at rt. Ethanol and acetonitrile were added and filtered off over filter. To the filtrate was added NaHCO3 solution and extracted with CH2Cl2. Organic layer was dried and evaporated to give crude N-(3-amino-4-bromophenyl)-3-(2-cyanopropan-2-yl)benzamide 62 (319 mg, 86%). (m/z)=358 and 360 (M+H)+.
