Reaction Steps
To a mixture of 2-nitro-4-(trifluoromethoxy)aniline (1.17 g) and EtOH (20 mL) were added ammonium chloride (565 mg) and water (5 mL), followed by further adding zinc powder (1.73 g) at 60° C., and heating and stirring at 60° C. for 1 hour. The reaction mixture was cooled to room temperature, filtered over Celite, and washed with EtOAc. This filtrate was washed with a saturated aqueous NaHCO3 solution and brine in this order, dried over MgSO4, and then concentrated under reduced pressure to obtain 4-(trifluoromethoxy)benzene-1,2-diamine.
