Versuchsvorschrift

0.4 ml of an HCl-saturated ether solution was added to a solution of 50.0 mg (0.16 mmol) of the compound from example 1i in 1 ml of ethylene glycol and stirred at RT for 1 h. The solution was then concentrated to dryness, and the residue was taken up in sat. NaHCO3 solution and extracted with EA several times. The combined EA extracts were dried, filtered and concentrated. The resulting residue was dried under high vacuum, resulting in 33 mg of the title compound in the form of a pale yellow oil.
