Versuchsvorschrift
This crude ester was dissolved in dioxan (50 ml) and concentrated hydrochloric acid (50 ml), and the solution was heated under reflux for 11/2 hours then concentrated under vacuum to give a brown solid. The solid was recrystallised from ethanol and from ethanol-water to give the title product (mp 248°-249° C. with decomposition).
