Participants

Reaction Steps

The compound obtained in Example 64 (300 mg, 0.81 mmol) was dissolved in 15 ml of tetrahydrofuran, 5 ml of water and 5 ml of methanol. 100 mg (2.44 mmol) of Lithium hydroxide monohydrate was added. The mixture was stirred at room temperature for 21 hours. At the end of reaction, tetrahydrofurane and methanol were removed by distillation under reduced pressure. To the distillate 1N HCl solution was added the mixture was extracted with ethylacetate. The extract was washed with saturated sodium chloride solution, dried over anhydrous magnesium sulfate, filtered. The filtrate was distilled under reduced pressure, and separated by column chromatography to obtain the title compound 20 mg (Yield 7%).
