実験手順

To the solution of the product from Example 205 (10 mg, 0.023 mmol) in N,N-dimethylformamide (0.2 mL) was added bromoacetonitrile (2.5 μL, 0.035 mmol) and potassium carbonate (5 mg, 0.035 mmol). The mixture was stirred while heating at 100° C. in a microwave reactor for 1 h. After cooling to 25° C., the orange solution was diluted with water and the pH of the aqueous layer was adjusted to pH 5 with acetic acid. The aqueous layer was extracted with ethyl acetate (3×20 mL). The combined organic layer was washed with water and brine, dried over magnesium sulfate, filtered, concentrated and purified by flash column chromatography on silica gel eluting with 1% methanol/dichloromethane to give the title compound as a yellow solid (6.0 mg, 55%). MS (ESI−) m/z 465 (M−H)−. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.99 (d, J=6.62 Hz, 6 H) 1.58 (m, 2 H) 1.68 (m, 1 H) 4.46 (m, 4 H) 6.92 (m, 1 H) 7.16 (m, 2 H) 7.49 (m, 1 H) 7.61 (d, J=9.19 Hz, 1 H) 8.56 (dd, J=7.90, 1.65 Hz, 1 H) 8.89 (m, 1 H) 14.00 (br s, 1 H) 15.39 (br s, 1 H). The sodium salt of the title compound was prepared according to the procedure of Example 1D. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.96 (d, J=6.62 Hz, 6 H) 1.48 (m, 2 H) 1.64 (m, 1 H) 4.31 (m, 4 H) 6.49 (t, J=6.62 Hz, 1 H) 6.99 (m, 2 H) 7.13 (m, 2 H) 8.35 (dd, J=7.72, 1.84 Hz, 1 H) 8.51 (dd, J=4.41, 1.84 Hz, 1 H) 15.73 (s, 1 H).
