Reaction Steps

To a suspended solution of (2-Chloro-5-nitro-phenyl)-acetonitrile (4.0 g, 20.0 mmol) in EtOH (10 mL) is added a solution of Sn(II)Cl2 (15.36 g, 81.0 mmol) in concentrated HCl (14 mL) at 75° C. After the mixture is stirred for 30 minutes at 75° C., the mixture is diluted with EtOAc and neutralized with K2CO3 until a pH of 8 is achieved. The organic layer is washed with saturated K2CO3, brine and dried, filtered and concentrated to give crude product, which is purified by recrystallization with CH2Cl2/EtOAc/Hexane to give the title intermediate as a solid (3.04 g, 89.7%).
