Versuchsvorschrift

A solution of the product of Example 2C (1.6 g, 3.0 mmol) in THF (30 mL) was treated with the product of Example 1F (0.57 g, 3.0 mmol), DEPBT (1.35 g, 4.5 mmol), and N,N-diisopropylethylamine (2.6 mL, 14.9 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 chromatographed on silica gel eluting with 50% ethyl acetate in chloroform, followed by. 5% methanol in chloroform to give the title compound (1.59 g, 75% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.79 (s, 9 H), 0.82 (s, 9 H), 1.51 (m, 2 H), 2.51 (m, 1 H),2.72 (m, 3 H), 3.49 (s, 3 H), 3.55 (s, 3 H), 3.63 (m, 1 H), 3.82 (d, J=9.93 Hz, 1 H), 3.90 (d, J=9.56 Hz, 1 H), 4.04 (m, 2 H), 4.86 (d, J=5.88 Hz, 1 H), 6.60 (d, J=9.93 Hz, 1 H), 6.78 (d, J=9.19 Hz, 1 H), 7.16 (m, 7 H), 7.31 (m, 1 H), 7.54 (d, J=8.46 Hz, 1 H), 7.83 (m, 5 H), 8.63 (d, J=4.78 Hz, 1 H).
