실험 절차

A solution of the product of Example 1H (0.18 g, 0.33 mmol) in THF (3.3 mL) was treated with the product of Example 1F (0.11 g, 0.60 mmol), DEPBT (0.15 g, 0.50 mmol), and N,N-diisopropylethylamine (0.29 mL, 1.66 mmol), stirred at 25° C. for 16 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 chromatographed on silica gel eluting with 0%-75% ethyl acetate in chloroform to give the title product (0.19 g, 81% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.75 (s, 9 H), 0.78 (s, 9 H), 1.28 (m, 2 H), 1.55 (m, 1 H), 2.70 (m, 4 H), 3.55 (d, J=11.77 Hz, 6 H), 3.85 (m, 3 H), 4.15 (m, 1 H), 4.80 (d, J=5.15 Hz, 1 H), 6.75 (d, J=9.19 Hz, 1 H), 6.86 (d, J=9.56 Hz, 1 H), 7.13 (m, 5 H), 7.22 (d, J=8.46 Hz, 2 H), 7.32 (m, 1 H), 7.52 (d, *8.82 Hz, 1 H), 7.88 (m, 5 H), 8.64 (d, j=4.41 Hz, 1 H).
