Procedure
The product of Example 249A (0.040 g, 0.097 mmol) in tetrahydrofuran (2.0 mL) and methanol (0.008 mL, 0.194 mmol) at 0° C. was treated with dropwise addition of a 2.0M solution of lithium borohydride in tetrahydrofuran (0.074 mL, 0.148 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 washed with water (2×5.0 ml) 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 0.93 (t, J=7.17 Hz, 3 H) 1.48 (m, 4 H) 2.77 (m, 2 H) 5.90 (t, J=6.99 Hz, 1 H) 7.07 (m, 1 H) 7.27 (m, 2 H) 7.58 (m, 3 H) 7.66 (d, J=8.09 Hz, 1 H) 8.08 (dd, J=8.09, 1.47 Hz, 1 H) 16.28 (s, 1 H).
