実験手順

A solution containing the product from Example 23Q (0.442 g, 0.95 mmol) in THF (10 mL) was treated with the product from Example 1F (0.20 g, 1.06 mmol), DEPBT (0.45 g, 1.50 mmol), and N,N-diisopropylethylamine (0.85 mL, 4.88 mmol), stirred at 25° C. for 1 hour, 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 0-75% ethyl acetate/dichloromethane to give the title compound (0.34 g, 56% yield).
