Procedure

A solution containing the product from Example 92J (0.049 g, 0.090 mmol) in THF (1 mL) was treated with the product from Example 1F (0.018 g, 0.095 mmol), DEPBT (0.040 g, 0.133 mmol), and N,N-diisopropylethylamine (0.080 mL, 0.459 mmol), stirred at 25° C. for 3 days, 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 reaction was purified by reversed phase chromatography on a C18 column eluting with 5-100% acetonitrile in water (0.1% TFA). The product was partitioned between ethyl acetate and 10% Na2CO3, and the organic phase was washed with brine and dried over MgSO4, filtered and concentrated to give the title compound (0.047 g, 73% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 0.79(s, 9H), 0.82(s, 9H), 1.58-1.43(m, 2H), 2.32(s, 3H), 2.79-2.68(m, 3H), 3.49(s, 3H), 3.55(s, 3H), 3.67-3.59(m, 1H), 3.843.80(d, J=9.93 Hz, 1H), 3.92-3.89(d, J=9.93 Hz, 1H), 4.19-4.01(m, 2H), 4.87-4.85(d, J=5.88 Hz, 1H), 6.63-6.60(d, J=9.19 Hz, 1H), 6.81-6.77(d, J=9.56 Hz, 1H), 7.19-7.12(m, 5H), 7.56-7.53(d, J=8.82 Hz, 1H), 7.68-7.64(m, 1H), 7.81-7.76(m, 3H), 7.86-7.83(d, J=8.09 Hz, 2H), 8.47(bs, 1H).
