To a solution of Example 2A (149 mg, 0.8 mmol) in THF (10 mL) was added triethylamine (0.4 mL) and adamantane-1-carbonyl chloride (0.2 g, 1 mmol). The mixture was heated to reflux overnight and then concentrated under reduced pressure. The residue was diluted with ethyl acetate, washed with 1 M NaHCO3, dried (Na2SO4), filtered and concentrated. The residue was purified by column chromatography (SiO2, 0-100% ethyl acetate:hexanes) to provide 25 mg of the title compound.
