Reaction Conditions

Reaction Steps

The product of Example 261A (0.048 g, 0.099 mmol) in tetrahydrofuran (2.0 mL) and methanol (0.008 mL, 0.198 mmol) at 0° C. was treated with dropwise addition of a 2.0M solution of lithium borohydride in tetrahydrofuran (0.074 mL, 0.149 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 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 4.10 (s, 2 H) 6.24 (t, J=6.43 Hz, 1 H) 7.19 (m, 1 H) 7.30 (m, 3 H) 7.43 (d, J=8.46 Hz, 1 H) 7.56 (m, 3 H) 7.67 (d, J=8.09 Hz, 1 H) 8.12 (d, J=7.72 Hz, 1 H) 15.95 (s, 1 H). MS (ESI−) m/z 485 (M−H)−.
