Reaction Steps

To a stirred solution of 6-hydroxy-7-methoxy-1-(3-ethoxy-benzyl)-isoquinoline-4-carbaldehyde (86 g, 0.24 mmol) in N,N-dimethylformamide (2 mL) was added potassium carbonate (337 mg, 2.40 mmol) and 1,3-dibromopropane (0.124 mL, 1.22 mmol) at room temperature. The reaction mixture was heated 85° C. for 2 hrs. The solvent was evaporated and the residue was purified on a flash chromatography (Merck Silica gel 60, 70–230 mesh, 50% ethyl acetate/hexane) to afford product 6-(3-bromo-propoxy)-7-methoxy-1-(3-ethoxy-benzyl)-isoquinoline-4-carbaldehyde as a colorless oil (70 mg, 62% yield).
