Participants

Reaction Steps

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 (60 mg, 0.11 mmol) is reacted with dichloroacetyl chloride (110 μL, 1.1 mmol). Following desilylation and precipitation, N-[4-({[(Z)-(6-bromo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)-2-hydroxyphenyl]-2,2-dichloroacetamide is obtained 8.8 mg, 16%).
