실험 절차

A solution of 8-[(cyclopropyl-isopropyl-amino)-methyl]-2,2,4,4-tetramethyl-chroman-6-carboxylic acid 4-benzyloxycarbonylmethyl-phenyl ester (Intermediate 40, 0.093 g, 0.17 mmol) in ethyl acetate (3 mL) was treated with a slurry of 10% palladium on carbon (20 mg) in ethyl acetate and the resulting reaction mixture was stirred under an atmosphere of hydrogen at ambient temperature for 2 h. The reaction mixture was filtered over a bed of celite and the filtrate was evaporated to a residue that was purified by flash column chromatography over silica gel to afford the title compound.
