1 ml of an aqueous 4N sodium hydroxide solution is added to a solution of 25.4 g (0.1 mol) benzoin isopropyl ether in 100 ml DMSO. The blue-green solution is mixed dropwise at 20°C with acrylic acid ethyl ester until the colour turns yellow (0.104 mol). After stirring for 2 hours, the product is worked up. The crystalline crude product is recrystallised from petroleum ether; melting point 52°-53°C. 86% of theory.
