Reaction Steps
To a suspension of 4-Methoxymethylene-4H-isoquinoline-1,3-dione (203 mg, 1.0 mmol) in N,N-dimethylformamide (2.5 mL) is added 1,4-phenylenediamine (108 mg, 1.0 mmol). The reaction mixture is shaken at 115° C. for 1.5 hours. Upon cooling to ambient temperature, product precipitated out of solution. The product is recovered by filtration, rinsing with diethyl ether, and drying to yield 205.9 mg 4-[(4-Amino-phenylamino)-methylene]-4H-isoquinoline-1,3-dione.
