Yield: 98%

Reaction Conditions:

with potassium hydroxide in tetrahydrofuran;ethanol;waterReflux;

Steps:

6.3 Synthesis Example 6. Synthesis of Compound 203. Synthesis Example 6-(3). Synthesis of Intermediate 6-c
In a 2-L round-bottom flask reactor, (86.0 g, 0.283 mol) was dissolved in ethanol (600 ml) and tetrahydrofuran (430 ml) and stirred. A solution of potassium hydroxide (47.6 g, 0.848 mol) in water (260 ml) was slowly added to the reactor, followed by stirring overnight under reflux. After completion of the reaction, the reaction mixture was cooled to room temperature. Extraction with ethyl acetate and water gave an organic layer which was then concentrated in a vacuum. The concentrate was stirred in excess ethanol and filtered. Recrystallization in methylene chloride and heptane afforded . (73.0 g, 98%)
