実験手順

A mixture of Example 438A (0.50 mmol) and 1M LiOH (0.60 mL) in THF (2 mL) was heated to 50° C., stirred for 3 hours, concentrated, dissolved in DMF (5 mL), and treated with a mixture of Example 77B (211 mg, 0.60 mmol), EDCI (193 mg, 1.0 mmol), and DMAP (50 mg). The mixture was stirred for 16 hours, treated with 1M HF (3 mL), stirred for 3 hours, diluted with ethyl acetate (100 mL), washed sequentially with 1M HCl (10 mL), water (20 mL), and brine (10 mL), dried (MgSO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 50-100% ethyl acetate/hexanes to provide the desired product.
