実験手順
A solution of 7-bromoquinaldine (22 g, 0.1M) and ethyl 4-(3-formylphenoxy)butanoate (20 g) in acetic anhydride (100 ml) was heated at 135° for 34 hours cooled and evaporated. Flash chromatography of the residue using 1:1 ether in hexane as eluant afforded crude adduct. Recrystallization from hexane ethyl acetate afforded the title compound: m.p. 92-93°.
