A solution containing the product from Example 3D (0.078 g, 0.171 mmol) in DMF (0.5 mL) was treated with the product from Example 4A (0.070 g, 0.205 mmol), EDAC (0.050 g, 0.261 mmol), HOBT (0.035 g, 0.259 mmol), and NMM (0.060 mL, 0.546 mmol) at 0° C., stirred at 25° C. for 16 hours and partitioned between ethyl acetate and water. The organic phase was washed with 10% citric acid, diluted sodium bicarbonate, and brine, dried over MgSO4, filtered and concentrated. The residue was purified by reversed phase chromatography on a C18 column, eluting with 5-100% acetonitrile in water (0.1% TFA) to give the title compound (0.030 g, 23% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.79 (m, 15 H), 1.00 (m, 1 H), 1.25 (m, 1 H), 1.51 (m, 2 H), 1.82 (m, 1 H), 2.64 (m, 5 H), 3.02 (m, 3 H), 3.55 (s, 3 H), 3.63 (m, 1 H), 3.82 (d, J=9.93 Hz, 1 H), 3.99 (d, J=11.03 Hz, 1 H), 4.13 (m, 2 H), 4.64 (d, J=7.72 Hz, 1 H), 4.80 (m, 2 H), 6.62 (d, J=9.93 Hz, 1 H), 6.98 (m, 5 H), 7.14 (m, 5 H), 7.32 (d, J=9.56 Hz, 1 H), 7.41 (d, J=4.41 Hz, 1 H), 7.62 (t, J=7.54 Hz, 1 H), 7.76 (m, 2 H), 8.06 (d, J=7.72 Hz, 1 H), 8.30 (d, J=8.46 Hz, 1 H), 8.88 (d, J=4.41 Hz, 1 H).
