実験手順

To a N,N-dimethylformamide (DMF) (10 ml) solution of (4-tert-butylphenoxy)acetic acid (50 mg, 0.2 mmol) and N-[4-(aminomethyl)-2-fluorophenyl]methanesulfonamide hydrochloride (40.4 mg, 0.2 mmol, J. Med. Chem. 2003, 46, 3116–3126), 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (EDC) (112 mg, 0.6 mmol), 1-hydroxybenzotriazole(HOBt) monohydrate (catalytic amount 5 mg) and triethylamine (0.3 ml) were added and the mixture was stirred for 3 hours at ambient temperature. The reaction mixture was then quenched with saturated aqueous solution of sodium bicarbonate and then crude products were extracted with methylene dichloride. The organic layer was then washed with brine and dried over sodium sulfate. After filtration to separate solvent and sodium sulfate, the solvent was removed under reduced pressure to give a residue, which was applied to a silica gel chromatography column and eluted with methylene dichloride/methanol=9/1 to furnish 0.59 g (75% yield) of the title compound as a white solid.
