Procedure

The product of Example 248A (0.103 g, 0.20 mmol) in tetrahydrofuran (2.0 mL) and methanol (0.015 mL, 0.42 mmol) at 0° C. was treated with dropwise addition of a 2.0M solution of lithium borohydride in tetrahydrofuran (0.15 mL, 0.30 mmol). The reaction was stirred at 25° C. for 1 hour, acidified with 1M hydrochloric acid to a pH of approximately 2-4, diluted with water, and the resulting precipitate was collected by filtration and dried. The crude product was chromatographed on silica gel with dichloromethane to give the title compound. The sodium salt of the title compound was prepared according to the procedure of Example 1D. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.21 (m, 4 H) 1.76 (m, 2 H) 2.31 (m, 1 H) 3.11 (m, 2 H) 3.97 (m, 1 H) 5.81 (d, J=19.85 Hz, 1 H) 7.05 (m, 1 H) 7.28 (m, 2 H) 7.53 (m, 2 H) 7.66 (d, J=8.09 Hz, 1 H) 7.75 (d, J=7.72 Hz, 1 H) 8.06 (dd, J=8.09, 1.47 Hz, 1 H). MS (ESI−) m/z 505 (M−H)−.
