Procedure

The compound prepared in (1) above (100 mg) was added to 3 ml of concentrated hydrochloric acid and heated at 80° C. with stirring for 1 hour. The mixture was cooled, alkalinized with the addition of sodium bicarbonate, and extracted with chloroform. The chloroform layer was dried over anhydrous sodium sulfate. The solvent was evaporated and the residue was subjected to silica gel column chromatography using chloroform-ethyl acetate (4:1) as an eluant to obtain fractions containing the target compound. The fractions were concentrated to produce 48 mg of the title compound.
