Procedure

640 mg (1.39 mmol) of the compound from Example 40A are dissolved in 30 ml of 1,2-dimethyoxyethane/water (2:1 v/v), mixed with 2.76 ml (2.76 mmol) of 1 N sodium hydroxide solution and stirred at room temperature for 30 min. The reaction mixture is then mixed with 20 ml of diethyl ether. The aqueous phase is separated off, adjusted to a pH of 4-5 with 1 N hydrochloric acid and extracted three times with ethyl acetate. The organic phases are combined and dried with magnesium sulfate. The volatile components are removed in a rotary evaporator. Drying in vacuo results in 335 mg (56% of theory) of the title compound in a purity of 94% (LC-MS).
