Potassium Carbonate → HCID 20600101, compound

Participants

Reaction Steps

A mixture of 0.5 g of methyl (E)-4-hydroxy-3-methoxycinnamate, 10 ml of 2-butanone, 0.35 ml of 6-bromohexanol and 1 g of ground potassium carbonate was heated under reflux for 5 hrs. Then, the reaction mixture was cooled and partitioned between ethyl acetate and water. The organic phase was dried over magnesium sulphate, filtered and evaporated. Chromatography on 100 g of silica gel with toluene/ethyl acetate (1:1) gave 750 ml of methyl (E)-3-[3-methoxy-4-(6-hydroxyhexyloxy)phenyl]acrylate as a colorless solid, λmax. (CH2Cl2): 323 nm (ε=20513).
