Reaction Conditions

Reaction Steps

To a stirred solution of 6-hydroxy-7-methoxy-1-(3-ethoxy-benzyl)-isoquinoline-4-carbaldehyde (60 g, 0.17 mmol) in N,N-dimethylformamide (2 mL) was added potassium carbonate (234 mg, 1.70 mmol) and 1-bromo-2-ethoxy-ethane (0.095 mL, 0.85 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 1-(3-ethoxy-benzyl)-6-(2-ethoxy-ethoxy)-7-methoxy-isoquinoline-4-carbaldehyde as a colorless oil (61 mg, 88% yield).
