実験手順
The compound of example 13 (1.92 g, 4.18 mmol) was dissolved in dioxane (40 ml), lithium hydroxide (10 ml, 1 M solution in water) was added and the mixture was stirred for 30 min at 60° C. The mixture was partitioned between 2 N hydrochloric acid and EA, the aqueous phase extracted with EA, and the combined organic extracts were washed with brine, dried over sodium sulfate, filtered and evaporated to dryness. The residue was stirred overnight in EA, filtered, and the crystals were dried in vacuo to give 1.35 g of the title compound.
