Procedure

The product of Example 262A (0.040 g, 0.082 mmol) in tetrahydrofuran (1.7 mL) and methanol (0.007 mL, 0.164 mmol) at 0° C. was treated with dropwise addition of a 2.0M solution of lithium borohydride in tetrahydrofuran (0.064 mL, 0.128 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 (5.0 mL), and the resulting precipitate was collected by filtration and dried. The crude product was triturated with dichloromethane/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 4.22 (m, 2 H) 6.38 (t, J=6.25 Hz, 1 H) 7.07 (t, J=7.54 Hz, 1 H) 7.28 (t, J=8.09 Hz, 2 H) 7.59 (m, 5 H) 8.08 (dd, J=8.09, 1.47 Hz, 1 H) 16.19 (s, 1 H). MS (ESI−) m/z 486 (M−H)−.
