Procedure

A solution containing the product from Example 2C (0.020 g, 0.038 mmol) in THF (0.4 mL) was treated with the product from Example 63C (0.013 g, 0.047 mmol), DEPBT (0.017 g, 0.057 mmol), and N,N-diisopropylethylamine (0.035 mL, 0.201 mmol) and the mixture was stirred at 25° C. for 45 minutes. The mixture was 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 0-100% ethyl acetate/dichloromethane to give the title compound (0.017 g, 57% yield). 1H NMR (300 MHz, DMSO-d) δ ppm 0.80(s, 9H), 0.81(s, 9H), 1.58-1.49(m, 2H), 2.74-2.72(m, 3H), 2.79(s, 3H), 3.49(s, 3H), 3.67-3.61(m, 1H), 3.84-3.81(d, J=9.93 Hz, 1H), 4.12-3.99(m, 1H), 4.16-4.13(d, J=8.82 Hz, 2H), 4.44(s, 2H), 4.82-4.80(d, J=5.88 Hz, 1H), 5.40-5.37(d, J=9.19 Hz, 1H), 6.62-6.59(d, J=9.93 Hz, 1H), 7.35-7.10(m, 13H), 7.67-7.64(d, J=8.82 Hz, 1H), 7.82-7.77(m, 1H), 7.88-7.84(m, 4H), 8.63 (d, J=4.41 Hz, 1 H).
