الإجراء التجريبي

144 mg (0.52 mmol) of the compound from Example 43A are initially charged in 0.5 ml of methanol, and 0.13 ml of 4 N hydrochloric acid are added. 3 drops of conc. hydrochloric acid are then added. The reaction mixture is stirred at RT for 8 h. The mixture is then diluted with about 5 ml of water and extracted three times with in each case 10 ml of diethyl ether. The combined organic phases are dried over magnesium sulfate and the solvent is removed on a rotary evaporator. The product obtained is used without further purification in the subsequent reaction.
