Reaction Steps

A mixture of 2-fluoro-4-nitro-5-(2-propynylamino)aniline (1.41 g) and 3,4,5,6-tetrahydrophthalic anhydride (1.33 g) was suspended in acetic acid (7 ml), followed by heating under reflux for 4 hours. The reaction mixture was cooled, water was added thereto, and the resultant mixture was extracted with ethyl acetate. The extract was washed with water and an aqueous sodium bicarbonate solution, dried and concentrated to give 2-[2-fluoro-4-nitro-5-(2-propynylamino)phenyl]-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione (0.85 g). m.p., 183.5° C.
