2-(4-Fluoro-3-nitrophenyl)-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione (5.8 g) was added to a mixture of glycine methyl ester hydrochloride (7.5 g), triethylamine (6 g) and 1,4-dioxane (50 ml), and the resultant mixture was heated under reflux for 4 hours, followed by addition of water and extraction with ethyl acetate. The extract was washed with water, dried and concentrated. The residue was crystallized from methanol to give 2-(4-methoxycarbonylmethylamino-3-nitrophenyl)-4,5,6,7-tetrahydro-2H-isoindole-1,3-dione (2.6 g). m.p., 220° C.
