실험 절차

35 mg (0.05 mmol) of the compound from Example 7A (trans isomer) are dissolved in 5 ml of dry THF, 18 mg (0.07 mmol) of tetra-n-butylammonium fluoride are added and the mixture is stirred at RT for 20 h. 15 ml of ethyl acetate are then added to the mixture. The mixture is washed twice with in each case 3 ml of saturated aqueous sodium bicarbonate solution. The organic phase is dried over magnesium sulfate. After removal of the solvent on a rotary evaporator the crude product is purified by preparative HPLC (column: YMC GEL ODS-AQ S-5/15 μm; mobile phase gradient: acetonitrile/water 10:90→95:5).
