Procedure

The product of Example 269A (0.12 g, 0.26 mmol) in tetrahydrofuran (5 mL) and methanol (0.021 mL, 0.52 mmol) at 0° C. was treated dropwise with a 2.0M solution of lithium borohydride in tetrahydrofuran (0.195 mL, 0.39 mmol). The reaction was stirred at 25° C. for 1 hour, acidified with 1M hydrochloric acid a pH of approximately 2-4, diluted with water (15 mL), and the resulting precipitate was collected by filtration and dried. The crude product was chromatographed on silica gel with 97:3 dichloromethane/methanol 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 1.04 (m, 2 H) 1.23 (m, 3 H) 1.52 (m, 1 H) 1.68 (m, 3 H) 1.87 (m, 2 H) 2.69 (m, 2 H) 5.95 (t, J=7.17 Hz, 1 H) 7.07 (d, J=5.52 Hz, 1 H) 7.19 (d, J=8.09 Hz, 1 H) 7.26 (t, J=7.72 Hz, 1 H) 7.53 (t, J=7.17 Hz, 1 H) 7.65 (d, J=6.99 Hz, 1 H) 7.78 (d, J=5.15 Hz, 1 H) 15.91 (s, 1 H).
