실험 절차

To a solution containing the product from Example 146C (0.035 g, 0.065 mmol) in tetrahydrofuran (0.70 mL) were added the product from Example 1F (0.012 g, 0.063 mmol), DEPBT (0.029 g, 0.097 mmol), and N,N-diisopropylethylamine (0.056 mL, 0.321 mmol) and the mixture was stirred at room temperature for 3 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 a C18 column, eluting with a gradient starting with water (containing 0.1% trifluoroacetic acid) and ending with acetonitrile to give the product (0.021 g, 46% yield). 1H NMR (300 MHz, MeOH-d6), δ ppm 0.86 (s, 9 H), 0.88 (s, 9 H), 1.61-1.71 (m, 2 H), 2.58-2.65 (m, 1 H), 2.76-2.96 (m, 4 H), 3.57 (s, 3H), 3.65 (s, 3 H), 3.74-3.79 (m, 1 H), 3.81 (s, 1 H), 3.1 (s, 1 H), 4.19-4.28 (m, 1 H), 4.30-4.40 (m, 1 H), 7.10-7.28 (m, 7 H), 7.56 (d, J=3.3 Hz, 1 H), 7.78 (d, J=8.1 Hz, 2 H), 7.83 (d, J=3.3 Hz, 1 H).
