Reaction Steps

Following the acetylation and desilylation procedure employed for the preparation of (2E)-N-[2-hydroxy-4-({[(Z)-(6-iodo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)phenyl]-2-methylbut-2-enamide, (4Z)-4-[({4-amino-3-[(triisopropylsilyl)oxy]benzyl}amino)methylene]-6-iodoisoquinoline-1,3(2H,4H)-dione (65 mg, 0.11 mmol) is reacted with acid chloride derived from 2-dimethylaminomethyl acrylic acid (Wissner, A.; Overbeek, E.; Reich, M. F.; Floyd, M. B.; Johnson, B. D.; Mamuya, N.; Rosfjord, E. C.; Discafani, C.; Davis, R.; Shi, X.; Rabindran, S. K.; et al. J. Med. Chem. 46; 1; 2003; 49-63, 0.18 g, 1.1 mmol). Following desilylation and precipitation, 2-[(dimethylamino)methyl]-N-[2-hydroxy-4-({[(Z)-(6-iodo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)phenyl]acrylamide is obtained as a solid (19 mg, 32%).
