Reaction Conditions

Reaction Steps

The product of Example 269A (0.116 g, 0.257 mmol) in tetrahydrofuran (5 mL) and methanol (0.021 mL, 0.514 mmol) at 0° C. was treated dropwise with a 2.0M solution of lithium borohydride in tetrahydrofuran (0.19 mL, 0.386 mmol). The reaction was stirred at 25° C. for 2 hour, acidified with 1M hydrochloric acid a pH of approximately 2-4, diluted with water (20 mL), and the resulting precipitate was collected by filtration and dried 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 3.97 (d, J=5.54 Hz, 2 H) 6.17 (t, J=6.43 Hz, 1 H) 7.08 (d, J=5.52 Hz, 1 H) 7.21 (d, J=8.09 Hz, 1 H) 7.33 (m, 4 H) 7.47 (d, J=6.62 Hz, 2 H) 7.55 (t, J=6.99 Hz, 1 H) 7.66 (d, J=7.35 Hz, 1 H) 7.73 (d, J=5.52 Hz, 1 H) 15.92 (s, 1 H). MS (ESI−) m/z 451 (M−H)−.
