Versuchsvorschrift

To a solution containing the product from Example 148E (0.17 mmol) in tetrahydrofuran (1.7 mL) were added the product from Example 1F (0.036 g, 0.190 mmol), DEPBT (0.077 g, 0.258 mmol), and N,N-diisopropylethylamine (0.15 mL, 0.861 mmol) and the mixture was stirred at room temperature for 18 hours. The mixture was partitioned between ethyl acetate and 10% Na2CO3 solution. The organic was washed with additional 10% Na2CO3 solution and then brine, dried over MgSO4, filtered and evaporated. The residue was chromatographed on reverse phase HPLC on C18 column eluting with a gradient starting with water and ending with methanol to give the product (0.044 g, 37% yield). 1H NMR (300 MHz, DMSO-d6), δ ppm 0.80 (s, 9 H), 0.82 (s, 9 H), 1.42-1.59 (m, 2 H), 2.67-2.79 (m, 3 H), 3.47 (s, 3 H), 3.59-3.67 (m, 1 H), 3.81 (d, J=9.6 Hz, 1 H), 3.91 (d, J=9.6 Hz, 1 H), 4.02-4.21 (m, 2 H), 4.87 (d, J=5.2 Hz, 1 H), 6.65 (d, J=9.6 Hz, 1 H), 6.80 (d, J=9.9 Hz, 1 H), 7.12-7.23 (m, 8 H), 7.45-7.55 (m, 4 H), 7.80 (d, J=8.5 Hz, 1 H), 8.01 (d, J=8.1 Hz, 1 H), 8.54 (d, J=4.8 Hz, 1 H), 8.83 (d, J=1.8 Hz, 1 H).
