Reaction Conditions

Reaction Steps

The product of Example 267A (0.055 g, 0.117 mmol) in tetrahydrofuran (2.0 mL) and methanol (0.010 mL, 0.234 mmol) at 0° C. was treated with dropwise addition of a 2.0M solution of lithium borohydride in tetrahydrofuran (0.088 mL, 0.176 mmol). The reaction was stirred at 25° C. for 1 hour, acidified with 1M 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 4.01 (s, 2 H) 6.25 (t, J=6.80 Hz, 1 H) 7.08 (t, J=7.35 Hz, 1 H) 7.28 (m, 2 H) 7.56 (m, 3 H) 7.68 (dd, J=8.09, 2.21 Hz, 2 H) 7.79 (d, J=8.09 Hz, 1 H) 7.86 (d, J=7.72 Hz, 1 H) 7.99 (s, 1 H) 8.09 (dd, J=7.91, 1.29 Hz, 1 H). (ESI−) m/z 470 (M−H)−.
