Procedure

7.8 g (23.4 mmol) (2,3-diphenyl-2-hydroxy-3-oxopropyl)-3-chloro-propionate was dissolved in 75 ml acetone. 4.9 g (35.1 mmol) K2CO3 and 50 mg BHT were added and the mixture was refluxed for 5 hours. The inorganic salts were removed by filtration and the solvent was evaporated under reduced pressure. The residue was treated with 50 ml n.-hexane, 2,3-diphenyl-2-hydroxy-3-oxopropyl acrylate was isolated by filtration and dried. 6.3 g of 2,3-diphenyl-2-hydroxy-3-oxopropyl acrylate (91%) was isolated. Based on 1H-NMR-analysis the conversion proved to be 98%.
