Procedure
A mixture of the product of Example 43B (50 mg, 0.068 mmol) and 4 drops of water in sulfuric acid (1 mL) was heated at 90° C. for 40 minutes. The mixture was poured onto ice water, neutralized with saturated sodium bicarbonate solution and extracted with ethyl acetate. The organic phase was dried over sodium sulfate, filtered and concentrated. The residue was purified by preparative HPLC using a gradient of 10/90 to 75/25 acetonitrile/water (containing 0.1% trifluoroacetic acid) to provide the title compound. 1H NMR (DMSO-d6, 300 MHz): δ 8.37 (s, 1H), 7.63(dd, J=2.1 Hz, J=9.3 Hz, 1H), 7.56 (s, 1H), 7.53 (s, 1H), 7.41 (m, 1H), 6.32 (t, J=9 Hz, 1H), 4.81 (s, 2H), 3.94 (s, 3H), 3.40 (m, 4H), 3.26 (m, 4H). MS: 544 (M+H+).
