Procedure

To a solution of toluene-4-sulfonic acid 2-(2,2-dimethyl-chroman-6-yl)-2-oxo-1-(3,4,5-trimethoxy-phenyl)-ethyl ester (21.6 mg, 0.04 mmol) in anhydrous ACN (0.5 mL) is added KF (4.72 mg, 0.08 mmol) and Kryptofix (30.6 mg, 0.08 mmol). After completion of addition the reaction mixture is heated to 90° C. After 15 minutes, the reaction mixture is cooled down to room temperature and diluted with water. The aqueous layer is separated and extracted with ethyl acetate (3×). All combined organic layers are dried over Na2SO4, filtered, and concentrated to yield an oil. The crude material is purified using reverse phase to yield the desired compound.
