Reaction Conditions

Reaction Steps

The product of Example 269A (0.051 g, 0.115 mmol) in tetrahydrofuran (5 mL) and methanol (0.01 mL, 0.23 mmol) at 0° C. was treated dropwise with a 2.0M solution of lithium borohydride in tetrahydrofuran (0.090 mL, 0.175 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 (10 mL), and the resulting precipitate was collected by filtration and dried. The crude product was chromatographed on silica gel with 97:3 dichloromethane/methanolto 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 1.16 (m, 5 H) 1.59 (m, 5 H) 3.01 (m, 1 H) 5.75 (d, J=3.31 Hz, 1 H) 7.15 (d, J=5.52 Hz, 1 H) 7.19 (d, J=7.72 Hz, 1 H) 7.26 (t, J=7.54 Hz, 1 H) 7.54 (m, 1 H) 7.65 (d, J=7.72 Hz, 1 H) 7.72 (d, J=5.52 Hz, 1 H) 15.93 (s, 1 H). MS (ESI−) m/z 443 (M−H)−.
