실험 절차

To a tetrahydrofuran (THF) (3.0 ml) solution of (4-tert-butyl-3,5-difluorophenoxy)acetic acid (166 mg, 0.68 mmol) was added 2-chloro-1,3-dimethylimidazolinium chloride (CDI) (110 mg, 0.68 mmol) at room temperature and the mixture was stirred for 2 hours, followed by the addition of triethylamine (0.5 ml) and N-{4-[(1R)-1-aminoethyl]-2-methylphenyl}methanesulfonamide hydrochloride (180 mg, 0.68 mmol) with stirring for 10 hours. The reaction was partitioned with water and dichloromethane and the organic layer was separated and dried over sodium sulfate. Then filtration and evaporation under reduced pressure gave the crude residue which was purified by silica gel column chromatography, eluting with dichloromethane/methanol from 5:1 to 5:2, to furnish 1 16mg (38%) of the title compound as a white solid.
