Procedure

2 ml of trans-cinnamaldehyde and 2.5 g of 4-methoxy acetophenone were dissolved in 50 ml of ethanol at room temperature. 10 ml of sodium hydroxide solution was then added and stirred for 12 h to form yellow solid precipitation. Filtering the precipitation to obtain the compound 1, with yield of 72% and purity of 96.3%. FIG. 1 and FIG. 2 respectively show the NMR and UV spectrum of compound 1; wherein the maximum adsorptive wavelength of compound 1 is 345 nm, and the adsorptive coefficient ε is 4.5×104, both listed on Table 1.
