実験手順
5-(2,4-Dichlorophenyl)-4-methylpenta-2,4-dienoic acid ethyl ester (2.37 g, 0.083 mol) was suspended in EtOH (50 mL). 2 N NaOH (13 mL, 3 eq) was added and the mixture was heated at 50° C. for 1 hour. The mixture was cooled to room temperature and acidified to pH 1. The resulting solid was collected to give 2 g of 5-(2,4-dichlorophenyl)-4-methylpenta-2,4-dienoic acid.
