Following the acetylation and desilylation procedure employed for the preparation of N-[2-hydroxy-4-({[(Z)-(6-iodo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)phenyl]benzamide, (4Z)-4-[({4-amino-3-[(triisopropylsilyl)oxy]benzyl}-amino)methylene]-6-bromoisoquinoline-1,3(2H,4H)-dione (54 mg, 0.10 mmol) is reacted with acryloyl chloride (41 μL, 0.50 mmol). Following desilylation, precipitation, and washing with methanol and diethyl ether, N-[4-({[(Z)-(6-bromo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)-2-hydroxyphenyl]acrylamide is obtained (8 mg, 18
