Versuchsvorschrift
The title compound from step 1 (6.80 g, 23 mmol) was dissolved in ether (100 mL), mixed with 5% H2SO4 (100 mL) and the solution vigorously stirred for 2 d at RT. The phases were separated and the ether phase discarded. The aqueous phase was made alkaline with 5N NaOH with ice cooling and extracted three times with ether, the combined organic phases were then washed with water, dried over Na2SO4 and concentrated to low volume in a vacuum.
