Versuchsvorschrift

According to general procedure 1, an amount of 3, 4 dihydroxybenzylamine (0.596 g, 4.3 mmol), is dissolved in N,N-dimethylformamide (61 mL). 1.8 ml (12.9 mmol) of triethylamine is added followed by 1.21 g (4.3 mmol) of (4E)-6-bromo-4-(methoxymethylene)isoquinoline-1,3(2H,4H)-dione. After the mixture is stirred at room temperature for 30 min, water (5 mL) is added and the reaction mixture is stirred for 60 min. The precipitate is filtered and washed several times with anhydrous ether. The crude solid is then purified by high performance liquid chromatography to give 910 mg of a white solid. MS (ESI) m/z 389.7 (M+1).
