実験手順
Potassium carbonate (0.125 g) was added to a solution of the compound (39) (0.689 g) in methanol, and the resultant mixture was stirred at room temperature for 2 hours. An additional amount (1.75 g) of potassium carbonate was added thereto, and the mixture was left on standing overnight. The crude product obtained after the usual work-up was subjected to silicagel column chromatography to give the monoalcohol (40).
