Reaction Steps

To a suspended solution of 3-(2,6-dichloro-3-nitro-phenyl)-1-methyl-1H-quinolin-2-one (50 mg, 0.143 mmol) in EtOH (3.0 mL) is added a solution of Sn(II)Cl2 (122 mg, 0.644 mmol) in concentrated HCl (2.0 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 (44.2 mg, 96.7%).
