Reaction Steps

Iron powder (1.22 g) was suspended in a 5% aqueous acetic acid solution, followed by heating at 80° C. A solution of 2-[2-fluoro-4-nitro-5-(2-propynyl)aminophenyl]-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione (0.75 g) in a mixture of acetic acid (2.2 ml) and ethyl acetate (2.2 ml) was dropwise added to the suspension, and the resultant mixture was heated at 70° C. for 3 hours. After removal of the precipitate by filtration, the filtrate was extracted with ethyl acetate. The extract was washed with water and an aqueous sodium bicarbonate solution, dried and concentrated to give 2-[4-amino-2-fluoro-5-(2-propynyl)aminophenyl]-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione (0.59 g). m.p., 182.2° C.
