Reaction Conditions

Reaction Steps

A solution of (4Z)-4-{[(4-amino-3-hydroxybenzyl)amino]methylene}-6-iodoisoquinoline-1,3(2H,4H)-dione (1.1 g, 2.3 mmol) in dimethylacetamide (12 mL) is cooled to 0° C. in an ice water bath. Acryloyl chloride (1.9 mL, 23 mmol) is added and the mixture is stirred at 0° C. for 15 minutes. The reaction mixture is then concentrated under reduced pressure and combined with impure material from a previous batch. The material is adsorbed onto flash silica gel, which is then subjected to flash chromatography (methanol/chloroform) to give N-[2-hydroxy-4-({[(Z)-(6-iodo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)phenyl]acrylamide (1.6 g).
