실험 절차

A solution of (2E)-3-(4-methoxyphenyl)-1-phenylprop-2-en-1-one (5 g, 20.98 mmol) and ethyl nitroacetate (2.32 ml, 20.98 mmol) in triethylamine (8.77 ml, 62.94 mmol) was stirred at 75° C. for 4 h. Ethyl acetate (500 ml) was added and the solution obtained was washed with HCl 1N (4×250 ml), dried over Na2SO4 and evaporated under reduced pressure, to obtain 7.21 g of ethyl 3-(4-methoxyphenyl)-2-nitro-5-oxo-5-phenylpentanoate.
