Reaction Conditions

Reaction Steps

The product of Example 269A (0.06 g, 0.13 mmol) in tetrahydrofuran (6 mL) and methanol (0.011 mL, 0.26 mmol) at 0° C. was treated dropwise with a 2.0M solution of lithium borohydride in tetrahydrofuran (0.1 mL, 0.2 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 98:2 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 0.86 (m, 4 H) 1.08 (m, 1 H) 1.29 (m, 3 H) 1.60 (m, 3 H) 1.93 (m, 1 H) 3.04 (m, 1 H) 5.76 (d, J=3.31 Hz, 1 H) 7.14 (d, J=5.52 Hz, 1 H) 7.19 (d, J=8.46 Hz, 1 H) 7.26 (t, J=7.54 Hz, 1 H) 7.52 (dt, J=8.46, 1.47 Hz, 1 H) 7.65 ((d, J=8.09 Hz, 1 H) 7.73 (t, J=5.15 Hz, 1 H) 15.93 (s, 1 H). MS (ESI−) m/z 457 (M−H)−.
