Reaction Steps

(4E)-6-iodo-4-(methoxymethylene)isoquinoline-1,3(2H,4H)-dione (0.12 g, 0.35 mmol), 3-amino-6-(4-methyl-piperazin-1-yl)-pyridin-2-ol (0.15 g, contaminated with triethylammonium trifluoroacetate) were coupled in N,N-dimethylformamide (3 mL) with triethylamine (0.27 mL). The mixture is heated in a 100° C. oil bath for three hours. The reaction mixture is purified by reverse phase HPLC to give (4Z)-4-({[2-hydroxy-6-(4-methylpiperazin-1-yl)pyridin-3-yl]amino}methylene)-6-iodoisoquinoline-1,3(2H,4H)-dione.2 trifluoroacetic acid salt (18 mg, 7.0%).
