Reaction Steps
The compound of Example 152 (2.74 g) was dissolved in ethanol (10 mL). To this solution, potassium hydroxide (330 mg) was added and the mixture was stirred at 50° C. overnight. Subsequently, the reaction mixture was diluted with water. 2 mol/L hydrochloric acid was then added and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated aqueous solution of sodium chloride and the organic phase was dried over anhydrous magnesium sulfate and was concentrated. The residue was purified on a silica gel column chromatography (hexane:ethyl acetate=10:1 shifted to 2:1) to give the desired product as a yellow oil (2.38 g).
