A solution of the product of Example 10F (27 mg, 0.051 mmol) in 4.0 N HCl in dioxane (4 mL) was stirred at 25° C. for 18 hours and concentrated in vacuo. A suspension of the residue in acetonitrile (2 mL) was treated with 1.0 N sodium hydroxide solution (51 μL, 0.051 mmol) and stirred at 25° C. for 1 h. The solution was lyophilized to afford the title compound (28 mg, 100%). 1H NMR (300 MHz, DMSO-d6): δ 16.82 (m, 1 H), 8.04 (d, J=7.35 Hz, 1 H), 7.47 (m, 2 H), 7.32 (t, J=7.35 Hz, 1 H), 6.95 (s, 1 H), 5.32 (t, J=5.70 Hz, 1H), 4.61 (m, 2 H), 2.09 (m, 2 H), 1.70 (m, 2 H), 1.02 (m, 4 H), 0.84 (m, 2 H), 0.67 (m, 6 H), 0.49 (s, 2 H).
