Reaction Conditions

Reaction Steps

In 21 mL of ethanol, 4.51 g (20 mmol) of 2-chloro-5-nitrobenzotrifluoride was dissolved, and a solution obtained by dissolving 3.8 g of zinc powder and 420 mg of ammonium chloride in 5 mL of water was added thereto, and the mixture solution was stirred at 70° C. for one hour. The reaction solution after removal of insolubles by filtration was concentrated, and the residue was partitioned between water and ethyl acetate, and the organic layer was washed with a saturated sodium chloride solution. The organic layer was dried, and then concentrated under reduced pressure, and to the obtained residue, 30 mL of a 4N hydrogen chloride ethyl acetate solution was added, and the formed white precipitate was collected by filtration, washed with ethyl acetate and vacuum dried to obtain 3.08 g (63%) of N-(4-chloro-3-(trifluoromethyl)phenyl)hydroxylamine hydrochloride.
