実験手順

The product of Example 305C (0.10 g, 0.23 mmol) was reacted with cesium carbonate (0.30 g, 0.92 mmol), 2-bromoacetamide (0.050 g, 0.37 mmol) and a catalytic amount of tetrabuylammonium iodide in N,N-dimethylformamide (5 mL) at 25° C. for 2 hours. The reaction was concentrated to half the volume under a stream of nitrogen warmed through a manifold heated to 165° C. The resulting solution was diluted with water and the precipitate was collected by filtration and dried to give the title compound (0.095 g, 85%). MS (ESI−) m/z 496 (M−H)−. The sodium salt of the title compound was prepared according to the procedure of Example 1D. 1H NMR (500 MHz, DMSO-d6) δ ppm 1.52 (m, 6 H) 1.76 (m, 2 H) 3.70 (m, 1 H) 4.47 (s, 2 H) 5.68 (d, J=4.88 Hz, 1 H) 7.03 (t, J=7.63 Hz, 1 H) 7.20 (m, 5 H) 7.46 (t, J=7.32 Hz, 1 H) 7.70 (d, J=8.54 Hz, 1 H) 8.06 (d, J=7.32 Hz, 1 H) 16.15 (s, 1 H).
