Reaction Steps

(4E)-6-bromo-4-(methoxymethylene)isoquinoline-1,3(2H,4H)-dione (0.42 g, 1.5 mmol) and C-(7-benzyloxy-2,2-dimethyl-benzo[1,3]dioxol-5-yl)-methylamine hydrochloride (1.5 mmol) were coupled in N,N-dimethylformamide (10 mL) with triethylamine (0.6 mL). The crude material is dissolved in a minimum of 7.5% methanol in chloroform and then passed through a Florisil plug, eluting with 5% methanol in chloroform. The filtrate is concentrated under reduced pressure to give (4Z)-6-bromo-4-({[(7-hydroxy-2,2-dimethyl-1,3-benzodioxol-5-yl)methyl]amino}methylene)isoquinoline-1,3(2H,4H)-dione as a light pink powder.
