実験手順
86 g of ethyl 2,3-dibromopropionate was added, over a 15-minute period, to a stirred mixture of 41 g of 6A, 97 g of potassium carbonate and 300 ml of acetone. The temperature of the mixture rose to 60° C. The mixture was refluxed for 19 hours, cooled to 30° C. and filtered. The solvent was evaporated from the filtrate under reduced pressure. The residue was recrystallized from hexane to give 6, mp: 71°-72° C.
