Reaction Steps

(4E)-6-bromo-4-(methoxymethylene)isoquinoline-1,3(2H,4H)-dione (67 mg, 0.24 mmol) and 5-(aminomethyl)-2-propoxybenzoic acid trifluoroacetate (50 mg, 0.16 mmol) were coupled in N,N-dimethylformamide (2 mL) and tetrahydrofuran (2 mL) with triethylamine (0.13 mL). The mixture is heated at 50° C. for 30 minutes and then at 65° C. overnight. Water is added and resulting mixture purified by reverse-phase HPLC to give a white solid material which is collected by filtration, washed with water, methanol, and diethyl ether and then dried under house vacuum to give 5-({[(Z)-(6-bromo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)-2-propoxybenzoic acid (42 mg, 59%).
