Reaction Steps

Fe powder (609 mg, 10.90 mmol) was added to a solution of ethyl 2-methyl-5-nitrophenyl ether (Intermediate 88, 395 mg) in a mixture THF/water (15 mL/5 mL) followed by ammonium chloride (583 mg, 10.90 mmol). The reaction mixture was stirred overnight under nitrogen. The reaction mixture was poured into water (20 mL) and the iron was filtrated. Ethyl acetate was used to wash the solid filtrated. The filtrate was extracted with ethyl acetate (3 times). The combined ethyl acetate layers were dried over sodium sulphate and concentrated to give the title compound (303 mg) which was directly used in the next step.
