Reaction Steps

After adding 110 mg of iron powder, 220 mg of ammonium chloride, 10 ml of ethanol and 2 ml of water to 4-(4-nitrophenoxy)-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid ethyl ester, the mixture was stirred at 80-85° C. for 2.5 hours. After returning the mixture to room temperature, 20 ml of tetrahydrofuran was added, the mixture was stirred for 5 minutes and filtered with celite, and 100 ml of ethyl acetate and 50 ml of water were added to the filtrate for liquid separation and extraction. The organic layer was washed with saturated saline, dried over anhydrous sodium sulfate, filtered with plug cotton and concentrated to dryness to obtain 90 mg of the title compound.
