실험 절차

Compound 53 (0.5 g) was dissolved in cold water (10 ml) containing concentrated ammonium hydroxide (2.5 ml). Benzyl chloride (0.5 ml) was added to this solution with stirring and the stirring continued at room temperature for 5 hours. The white solid (0.41 g) which had separated from solution was collected by filtration, washed with cold water. The solid was extracted with ethyl acetate (100 ml) and the ethyl acetate phase was dried over anhydrous Na2SO4 and then evaporated by aspirator to give a syrup. The syrup was subjected to a flash column of silica gel with CH2Cl2 --MeOH (15:1) as eluant. Fractions were collected (25 ml each) and fractions containing the desired compound were combined and evaporated to afford 54 which was crystallized from CH2Cl2 --MeOH (15:1), mp. 149° C., Yield 0.223 g (35.5%).
