실험 절차

The compound obtained in (8) above (1.66 gm) was dissolved into a mixed solvent of 70 ml of ethanol and 10 ml of THF. To the solution were added 2 ml of triethylamine and 1.5 ml of ethyltrifluoroacetate, followed by stirring for 20 hours at 20° C. The reaction product was added to dilute aqueous solution of hydrochloric acid and extracted with chloroform. The extract was washed with water, saturated sodium bicarbonate and saturated brine in this order, and dried over anhydrous sodium sulfate. After removal of the solvent by evaporation, the residue was subjected to silica gel column chromatography using chloroform as an eluant to obtain fractions containing the target compound. The fractions were concentrated to obtain 1.79 gm of the title compound.
