Procedure

6-Hydroxyquinoline (25.1 g), methyl 2-bromobutyrate (32.3 g) and anhydrous potassium carbonate (23.0 g) in dry N,N-dimethylformamide (100 ml) were stirred at 100° C. for 3 hours then stored at ambient temperature for 18 hours. The mixture was added to water, extracted with ethyl acetate (three times) and the extracts combined, washed with water (four times) then dried over magnesium sulphate. The solvent was evaporated under reduced pressure to give the required product (39.0 g) as a red oil.
