実験手順

4 g (11.1 mmol) of methyl 3-(2-acetoxyethoxy)-2-hydroxy-3,3-di-phenylpropionate were dissolved in 20 ml of DMF under N2, 770 mg (5.6 mmol) of K2CO3 and 2.24 g (11.1 mmol) of 2-methanesulfonyl-4-methoxy-6-methylpyrimidine were added, and the mixture was stirred at 80° C. for 2 h. It was subsequently diluted with 20 ml of H2O and extracted twice with 30 ml of diethyl ether, the organic phase was dried over MgSO4 and concentrated, and the residue was purified by chromatography on silica gel with ethyl acetate/cyclohexane mixtures. 4.8 g (90%) of a colorless oil were obtained.
