Versuchsvorschrift

2.8 g of p-hydroxy cinnamic acid was dissolved in 3 ml of DMSO, and 10 mg of sodium hydride of which the oil was washed by hexane was added. The mixture was stirred and heated to 90° C. under a flow of N2 gas. 5.0 g of glycidol was added gradually, heating and agitation were carried out for 1.5 hours, neutralized by adding hydrochloric acid and then the adduct of cinnamic acid and glycerin was obtained.
