To a mixture of water (50 mL) and iron powder (0.88 g, 15.8 mmol) at 65° C. was added concentrated hydrochloric acid (1 mL) dropwise and the mixture was stirred for 15 min. The aqueous layer of the mixture was poured out, and a solution of N-(2-(adamantan-1-yl)ethyl)-2-fluoro-4-nitroaniline (0.5 g, 1.57 mmol) in MeOH (50 mL) was added to the above processed iron powder. The mixture was further stirred at 65° C. for 30 min. The mixture was then cooled to rt and filtered. The filtrate was concentrated and the residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=4:1) to give the title compound as a white solid (382 mg, 84%).
