Reaction Steps

A solution containing the product from Example 59E (0.025 g, 0.070 mmol) in a mixture of THF (0.3 mL) and water (0.3 mL) was treated with lithium hydroxide monohydrate (0.004 g, 0.094 mmol), and the mixture was stirred at 25° C. for 18 hours. The solvent was concentrated to give the crude product, which was used without purification.
