Procedure

To a solution of 4-chloro-N-methyl-2-nitroaniline (713 mg, 3.8 mmol) in ethanol (10 mL) is added ammonium formate (1.2 g, 19 mmol) followed by zinc dust (745 mg, 11.5 mmol). The reaction is heated to 50° C. for 2 h. The room temperature suspension is filtered through a bed of Celite and the filtrate is rinsed with additional methanol (10 mL). The filtrate is concentrated to afford the title compound (592 mg, 89%) as an oil which was used in the next step without purification

Workup

  1. filtrationThe room temperature suspension is filtered through a bed of Celite
  2. washthe filtrate is rinsed with additional methanol (10 mL)
