Procedure

A solution containing the product from Example 2C (0.082 g, 0.154 mmol) in THF (1.5 mL) was treated with the product from Example 123A (0.057 g, 0.17 mmol), DEPBT (0.069 g, 0.231 mmol), and N,N-diisopropylethylamine (0.135 mL, 0.77 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 chromatographed on silica gel eluting with 0-100% acetate/dichloromethane, followed by 0-5% methanol in ethyl acetate to give the title compound (0.080 g, 61% yield).
