Procedure

A solution containing the product from Example 8B (2.0 g, 4.40 mmol) in DMF (10 mL) was treated with the product from Example 15C (1.34 g, 4.39 mmol), EDAC (1.01 g, 5.27 mmol), HOBT (0.7 g, 5.19 mmol), and NMM (0.96 mL, 8.72 mmol), stirred at 25° C. for 16 hours, treated with Example 15C (0.13 g), EDAC (0.5 g), HOBT (0.35 g), NMM (1 mL), and DMF (5 mL), stirred for 64 hours at 25° C. and concentrated. The concentrate was partitioned between ethyl acetate and saturated NaHCO3. The organic phase was washed with brine, dried over Na2SO4, filtered and concentrated. The residue was chromatographed on silica gel eluting with 0-4% methanol/dichloromethane to give the title compound (1.76 g, 54% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.68 (d, J=6.62 Hz, 3 H), 0.81 (m, 15 H), 1.26 (m, 1 H), 1.49 (m, 2 H), 1.78 (m, 1 H), 2.45 (m, 5 H), 2.70 (m, 3 H), 2.90 (m, 2 H), 3.04 (m, 2 H), 3.59 (m, 4 H), 3.87 (m, 2 H), 4.13 (m, 2 H), 4.31 (s, 2 H), 4.79 (d, J=5.52 Hz, 1 H), 6.80 (d, J=9.19 Hz, 1 H), 7.05 (s, 3 H), 7.19 (m, 5 H), 7.51 (m, 2 H), 7.86 (d, J=8.82 Hz, 1 H), 8.36 (d, J=3.68 Hz, 1 H).
