Procedure

To a solution of the product of Example 2C (0.275 g, 0.517 mmol) in tetrahydrofuran (0.40 mL) were added the product from Example 174E (0.15 g, 0.519 mmol), DEPBT (0.233 g, 0.779 mmol), and N,N-diisopropylethylamine (0.45 mL, 2.58 mmol), and the mixture was stirred at room temperature for 2 hours. The reaction was partitioned between ethyl acetate and 10% Na2CO3 solution. The organic layer was washed with additional 10% Na2CO3 solution and brine, dried over MgSO4, filtered and concentrated. The residue was chromatographed on silica gel eluting with a gradient starting with dichloromethane and ending with ethyl acetate to give the title compound (0.214 g, 50% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.80 (m, 15 H), 1.39 (s, 9 H), 1.47-1.56 (m, 2 H), 1.99 (s, 3 H), 2.72-2.79 (m, 3 H), 3.49 (s, 3 H), 3.62-3.65 (m, 2 H), 3.80-3.84 (m, 2 H), 4.05 (d, J=9.9 Hz, 1 H), 4.10-4.24 (m, 2 H), 4.94 (d, J=4.8 Hz, 1 H), 6.60-6.65 (m, 2 H), 7.10-7.21 (m, 8 H), 7.29-7.31 (m, 1 H), 7.52 (d, J=8.8 Hz, 1 H), 7.77 (d, J=8.5 Hz, 1 H), 7.82-7.89 (m, 4 H), 8.64 (m, 1 H).
