Procedure

A mixture of Example 470F (75 mg, 0.2 mmol), lithium hydroxide (70 mg, 2.0 mmol), dioxane (1.5 mL), and water (0.75 mL) was sealed in a vial and microwaved at 160° C. for 15 minutes. Purification by preparative HPLC on a Waters Symmetry C8 column (25 mm×100 mm, 7 μm particle size) using a gradient of 10% to 100% acetonitrile/10 mmol aqueous ammonium acetate over 8 minutes (10 minute run time) at a flow rate of 40 mL/min provided the desired compound. MS (ESI(+)) m/e 432, 434 (M+H)+; (ESI(−)) m/e 430, 432 (M−H)−; 1H NMR (300 MHz, DMSO-d6) δ 7.68 (m, 1H), 7.57 (m, 1H), 7.28 (m, 3H), 3.65 (s, 3H), 2.49 (m, 4H), 1.09 (t, 3H).
