実験手順
0.9 g of the compound obtained in Step B is stirred for 2 hours at ambient temperature in a solution of 10 ml of dioxane, 0.8 ml of pyridine and 0.42 ml of trifluoroacetic anhydride. After evaporating off the solvent, chromatography of the residue on silica gel (dichloromethane/ethyl acetate: 96/4) enables isolation of the expected product, which crystallises in heptane.
