Procedure

The product of Example 252A (0.058 g, 0.134 mmol) in tetrahydrofuran (3.0 mL) and methanol (0.010 mL, 0.268 mmol) at 0° C. was treated with dropwise addition of a 2.0M solution of lithium borohydride in tetrahydrofuran (0.105 mL, 0.210 mmol). The reaction was stirred at 25° C. for 1 hour, acidified with 1 M hydrochloric acid to a pH of approximately 2-4, diluted with water (6.0 mL), and the resulting precipitate was collected by filtration and dried. The crude product was triturated with diethyl ether and filtered 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 4.03 (s, 2 H) 6.20 (t, J=6.07 Hz, 1 H) 6.35 (m, 1 H) 7.05 (t, J=7.72 Hz, 1 H) 7.29 (t, J=7.72 Hz, 3 H) 7.46 (t, J=7.72 Hz, 1 H) 7.56 (m, 2 H) 7.67 (d, J=7.72 Hz, 2 H) 8.06 (d, J=8.09 Hz, 1 H) 16.24 (s, 1 H). MS (ESI−) m/z 435 (M−H)−.
