Procedure

A solution containing the product from Example 92J (0.050 g, 0.092 mmol) in THF (1 mL) was treated with the product from Example 70A (0.028 g, 0.097 mmol), DEPBT (0.041 g, 0.137 mmol), and N,N-diisopropylethylamine (0.080 mL, 0.459 mmol), stirred at 25° C. for 16 hours, 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 residue 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 saturated NaHCO3, and the organic phase was washed with brine and dried over MgSO4, filtered and concentrated to give the title compound (0.036 g, 48% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 0.83(s, 9H), 0.89(s, 9H), 1.60-1.49(m, 2H), 2.32(s, 3H), 2.60-2.53(m, 1H), 2.68-2.65(d, J=6.99 Hz, 2H), 2.88-2.75(m, 2H), 2.96-2.90(q, J=8.70 Hz, 1H), 3.24-3.15(m, 1H), 3.51(s, 3H), 3.71-3.61(m, 1H), 3.87-3.83(d, J=9.56 Hz, 1H), 4.09(s, 1H), 4.22-4.11 (m, 2H), 4.31(s, 2H), 4.56-4.53(d, J=7.72 Hz, 1H), 6.67-6.63(d, J=9.56 Hz, 1H), 7.08-7.02(m, 5H), 7.21-7.19(d, J=8.46 Hz, 2H), 7.31-7.26(m, 3H), 7.40-7.35(m, 2H), 7.50-7.46 (d, J=9.56 Hz, 1H), 7.68-7.64(dd, J=8.27, 2.02 Hz, 1H), 7.82-7.77(m, 2H), 7.88-7.85(d, J=8.09 Hz, 2H), 8.47-8.46(d, J=2.21 Hz, 1H).
