Reaction Steps

The compound of step 2 (274 mg, 0.883 mmol) was dissolved in dioxane (4.5 ml), lithium hydroxide (4.42 ml of a 1 M aqueous solution, 4.42 mmol) was added, and the mixture was stirred at 60° C. for 30 min. The mixture was partitioned between 2 N hydrochloric acid and EA, the aqueous phase extracted with EA, and the combined organic extracts were dried over sodium sulfate, filtered and evaporated to dryness. The residue was purified by preparative RP HPLC (water/ACN gradient) to give 160 mg of the title compound.
