To the title compound of Example 12 Step A (0.1 mmol, 50 mg) in 800 μL of dioxane was added LiOH (0.4 mmol, 10 mg) in 400 μL of H2O. The resulting solution was stirred at 40° C. overnight. The reaction mixture was taken up in aqueous pH 7 buffer and EtOAc, and acidified with 2 N HCl until two clear layers formed after agitation. The organic layer was collected and the aqueous layer was washed with EtOAc. The combined organic layers were dried with MgSO4 and concentrated under reduced pressure to afford the acid as a white solid, which was used without further purification. (HPLC A: 1.97 min).
