Reaction Steps

To a suspension of 4-Methoxymethylene-4H-isoquinoline-1,3-dione (40.6 mg, 0.2 mmol) in N,N-dimethylformamide (0.5 mL) is added 3,4-dihydroxyaniline (25 mg, 0.2 mmol). The reaction mixture is shaken at 115° C. for 1.5 hours. The reaction mixture is diluted to 2 mL with N,N-dimethylformamide and purified by C18 reverse phase HPLC. The pure fractions were combined and concentrated to yield the title compound (15.6 mg).
