Reaction Steps
115.5 g (0.525 mol) of 3-allyloxy-4-hydroxy-cinnamic acid are dissolved in 530 ml of 2 N sodium hydroxide solution, 800 g of ice are added and 107 g (1.05 mols) of acetic anhydride are introduced dropwise over the course of quarter of an hour at 0°-5° C, whilst stirring. The crystals which have precipitated are then filtered off, suction-dried and recrystallised from chloroform. 3-Allyloxy-4-acetoxy-cinnamic acid of melting point 154°-155° C is obtained.
