Reaction Steps
430 mg of 6-(1,4-dioxa-spiro[4.5]dec-8-yloxy)-2-phenyl-chroman were dissolved at room temperature in 5 ml of tetrahydrofuran. 5 ml of 10% aqueous hydrochloric acid were added and stirring at room temperature was continued for 16 h. The reaction mixture was diluted with ethyl acetate and the organic layer washed with saturated aqueous solution of sodium hydrogencarbonate. The organic layer was dried with sodium sulfate and filtered, and the volatile components removed under reduced pressure. 357 mg of the title compound were obtained as a pale yellow solid.
