Procedure

A solution containing the product from Example 89C (0.032 g, 0.059 mmol) in THF (0.5 mL) was treated with the product from Example 1F (0.014 g, 0.076 mmol), DEPBT (0.034 g, 0.114 mmol), and N,N-diisopropylethylamine (0.066 mL, 0.38 mmol) and the mixture was stirred at 25° C. for 16 hours. 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 purified by chromatography on silica gel eluting with 0-100% ethyl acetate/dichloromethane, followed by 0-5% methanol in ethyl acetate, to give the title compound (0.028 g, 61% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 0.77 (s, 9H), 0.83(s, 9H), 1.58-1.39(m, 2H), 2.32(s, 3H), 2.77-2.69(m, 3H), 3.51(s, 3H), 3.54(s, 3H), 3.67-3.60(m, 1H), 3.81-3.78(d, J=9.93 Hz, 1H), 3.95-3.92(d, J=9.93 Hz, 1H), 4.17-4.01(m, 2H), 4.86-4.84(d, J=5.52 Hz, 1H), 6.63-6.60(d, J=9.56 Hz, 1H), 6.78-6.75(d, J=9.93 Hz, 1H), 7.14-7.06(m, 5H), 7.29-7.26(d, J=8.46 Hz, 2H), 7.61-7.58(d, J=9.19 Hz, 1H), 7.68-7.65(m, 1H), 7.80-7.73(m, 2H), 7.90-7.87(d, J=8.09 Hz, 2H), 8.47(s, 1H).
