Procedure

8-[4-Methoxy-3-(2-m-tolyl-ethoxy)-benzoylamino]-1,4-dioxa-spiro[4.5]decane-8-carboxylic acid methyl ester (4.7 g, 9.7 mmol; intermediate in the synthesis of example 54) was dissolved in dioxane (70 ml), 2 N aqueous hydrochloric acid (10 ml) was added and the mixture was stirred at room temperature overnight. The material was partitioned between EA and saturated aqueous sodium chloride solution, the aqueous phase was extracted with EA, the combined organic phases were dried over sodium sulfate and evaporated to dryness to yield the title compound.
