Versuchsvorschrift

To a solution of 0.2 g (0.56 mmole) of 59 in 20 ml of CH2Cl2, was added 8 g of 50% NaOH and one drop of Aliquat-336 (methyltricaprylylammonium chloride) phase transfer catalyst. The reaction mixture was stirred for 10 h at room temperature. Twenty g of ice was added to the mixture and the mixture was extracted with CH2Cl2 (3×10 ml) washed with water, brine and dried over MgSO4 and concentrated in vacuo to recover 0.15 g of crude product. This was recrystallized from Hexane/EtOAc to give 125 mg of white crystal, mp 209-210° C. Proton and carbon NMR and mass spectra were consistent with the product.
