Reaction Steps

The product of Example 269A (0.046 g, 0.10 mmol) in tetrahydrofuran (5 mL) and methanol (0.005 mL, 0.12 mmol) at 0° C. was treated dropwise with a 2.0M solution of lithium borohydride in tetrahydrofuran (0.06 mL, 0.12 mmol). The reaction was stirred at 25° C. for 3 hour, acidified with 1M hydrochloric acid a pH of approximately 2-4, diluted with water (10 mL), and the resulting precipitate was collected by filtration and dried. The crude product was chromatographed on silica gel with 99:1 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 1.26 (m, 3 H) 4.49 (m, 1 H) 5.90 (m, 1 H) 7.20 (d, J=8.09 Hz, 1 H) 7.27 (t, J=8.46 Hz, 2 H) 7.30 (m, 5 H) 7.54 (m, 2 H) 7.66 (d, J=8.09 Hz, 1 H) 15.93 (s, 1 H). MS (ESI−) m/z 465 (M−H)−.
