Versuchsvorschrift

A solution of 8 (1.15 g) in 6N HCl (10 mL) was heated at 60° C. for 4 hours. After cooling to room temperature, the solution was neutralized with 6N NaOH solution. The aqueous mixture was extracted with EtOAc (2×30 mL), the combined organic layers were washed with brine (1×50 mL) and dried over MgSO4. The solids were filtered, and the filtrate was concentrated under reduced pressure to give the desired product as an oil (0.68 g).
