To a suspension of 4-Methoxymethylene-4H-isoquinoline-1,3-dione (406 mg, 2.0 mmol) in N,N-dimethylformamide (250 μL) is added 4-aminobenzylamine (244 mg, 2.0 mmol). The reaction mixture is shaken at 115° C. for 1.5 hours, then concentrated. Ethyl acetate is added to the solid residue that remained and the solid is recovered by filtration, rinsing with diethyl ether, and drying to yield 555.5 mg of 4-[(4-Amino-benzylamino)-methylene]-4H-isoquinoline-1,3-dione.
