Procedure

A solution containing the product from Example 1H (0.025 g, 0.047 mmol) in THF (0.5 mL) was treated with the product from Example 59F(0.070 mmol), DEPBT (0.021 g, 0.070 mmol), and N,N-diisopropylethylamine (0.041 mL, 0.240 mmol) and the mixture was stirred at 25° C. for 2 hours. The mixture was 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 product was purified by reversed phase chromatography on a C18 column eluting with 5-100% acetonitrile in water (0.1% TFA). The reaction was partitioned between ethyl acetate and saturated NaHCO3, and the organic phase was washed with brine and dried over MgSO4, filtered and concentrated, to give the title compound (0.021 g, 50% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.81 (s, 9 H), 0.88 (s, 9 H), 1.38 (m, 1 H), 1.53 (m, 1 H), 2.40 (m, 1 H), 2.64 (m, 3 H), 2.83 (m, 1 H), 3.12 (m, 4 H), 3.54 (m, 4 H), 3.82 (m, 3 H), 3.95 (m, 1 H), 4.03 (s, 1 H), 4.18 (m, 1 H), 4.43 (d, J=6.99 Hz, 1 H), 4.60 (m, 2 H), 6.92 (m, 4 H), 7.04 (m, 2 H), 7.21 (m, 4 H), 7.32 (m, 1 H), 7.58 (m, 3 H), 7.89 (m, 5 H), 8.65 (d, J=4.41 Hz, 1 H).
