Procedure
To a THF (100 mL) solution of triethyl phosphonoacetate (44.0 mL) was slowly added NaH (60% dispersion in mineral oil, 8.8 g) at 0° C. After stirring for 1 hour, a THF (200 mL) solution of 3,5-dimethyl-4-[(5-nitropyridin-2-yl)oxy]benzaldehyde (54.5 g) was added to the reaction mixture. After stirring at room temperature for 2 hours, AcOEt and H2O were added to the reaction mixture. The resulting precipitate was collected to give ethyl (E)-3-{3,5-dimethyl-4-[(5-nitropyridin-2-yl)oxy]phenyl}prop-2-enoate as a white powder (40.9 g).
