Procedure

A solution containing the product from Example 2C (1.1 g, 2.07 mmol) in THF (20 mL) was treated with the product from Example 15C (0.87 g, 2.07 mmol), DEPBT (0.93 g, 3.11 mmol), and N,N-diisopropylethylamine (1.8 mL, 10.33 mmol), stirred at 25° C. for 3 hours, and partitioned between ethyl acetate and 10% Na2CO3 solution. The organic phase was washed with additional 10% Na2CO3 solution and brine, dried over MgSO4, filtered and concentrated. The residue was purified by chromatography on silica gel eluting with a gradient starting with 0-100% ethyl acetate/dichloromethane, followed by 0-10% methanol in ethyl acetate to give the title compound (1.17 g, 69% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.83 (m, 18 H), 1.29 (m, 1 H), 1.53 (m, 2 H), 1.80 (m, 1 H), 2.48 (s, 3 H), 2.72 (m, 3 H), 2.96 (m, 3 H), 3.50 (s, 3 H), 3.65 (m, 1 H), 3.84 (d, J=9.93 Hz, 1 H), 3.94 (d, J=11.03 Hz, 1 H), 4.15 (m, 2 H), 4.32 (s, 2 H), 4.67 (d, J=7.35 Hz, 1 H), 6.64 (d, J=9.93 Hz, 1 H), 7.09 (m, 5 H), 7.22 (m, 3 H), 7.31 (m, 2 H), 7.52 (dd, J=7.72, 1.47 Hz, 1 H), 7.86 (m, 5 H), 8.36 (dd, J=4.78, 1.47 Hz, 1 H), 8.63 (d, J=4.41 Hz, 1 H).
