Reaction Steps

An amount of 4-difluoromethoxy-3-hydroxy benzylamine hydrochloride (113 mg, 0.50 mmol), is dissolved in N,N-dimethylformamide (5 mL), triethylamine (50 μL 0.75 mmol) is added followed by (4E)-6-iodo-4-(methoxymethylene)isoquinoline-1,3(2H,4H)-dione (165 mg, 0.50 mmol). After the mixture is stirred at room temperature for 30 min, the solvent is removed in-vacuo and the residue dissolved in 7.5% methanol in chloroform and passed thru a short pad of Florisil eluting with 7.5% methanol in chloroform, the eluate is evaporated and the solid triturated with ether, filtered and washed several times with anhydrous ether to give 193 mg of (4Z)-6-Iodo-4-{[(4-difluoromethoxy-3-hydroxybenzyl)amino)methylene}isoquinoline-1,3(2H,4-dione as a beige solid (79% yield); mp 254-5° C., MS data ES(−) 485.0 m/e.
