실험 절차

A mixture of EXAMPLE 173A (0.4 g), dihydro-2H-pyran-4(3H)-one (0.179 g), sodium cyanoborohydride (0.112 g), and acetic acid (0.5 mL) in tetrahydrofuran (3 mL) was stirred overnight. The solvents were removed under reduced pressure. The residue was purified with flash column chromatography on silica gel eluting with 100:5:0.5 ethyl acetate/methanol/NH4OH to give the desired product.
