実験手順

17.75 gm of the compound prepared in (3) above was dissolved into 200 ml of dry pyridine. To this was slowly added 24.25 gm of p-toluenesulfonyl chloride at 0° C. and the mixture was stirred for 3 hours at room temperature. After the addition of 300 ml of ether, the mixture was washed with water, followed by the addition of 6 N hydrochloric acid to acidify it and washing with saturated brine. The product was dried over anhydrous sodium sulfate and the solvent was evaporated to obtain 31.3 gm of the title compound.
