実験手順

To a solution of the compound (30 mg) of Example 1 and triethylamine (18 μL) in dichloromethane (10 mL) was added dropwise pivaloyl chloride (13 mg) in dichloromethane (1 mL) on an ice bath. After stirring for 30 minutes, the solvent was removed at reduced pressure, the residue was purified by silica gel column chromatography (hexane/ethyl acetate), and the title compound (35 mg) was obtained as a colorless amorphous substance.
