Participants

Reaction Conditions

Reaction Steps

To a solution of 5-bromo-N-methyl-2-nitroaniline (10 g, 43.5 mmol) in EtOH/H2O (700 mL) was added Fe (14.6 g, 261 mmol), ammonium chloride (14 g, 261 mmol) and the reaction mixture was heated at 60° C. for 4 h. The crude reaction mixture was filtered, concentrated, dissolved in ethyl acetate, washed with brine, dried over sodium sulfate, filtered and concentrated. The crude product was used in next reaction without further purification. (7.9 g, yield 90%) MS (ESI+) e/z: 202.1.
