To a N,N-dimethylformamide (DMF) (15 ml) solution of (4-tert-butylphenoxy)acetic acid (312 mg, 1.50 mmol) and N-[4-(aminomethyl)-2-methylphenyl]methanesulfonamide hydrochloride (451 mg, 1.80 mmol), 1-ethyl-3-(3′-dimethylaminopr6pyl)carbodiimide hydrochloride (EDC) (518 mg, 2.70 mmol), 4-(dimethylamino)pyridine (DMAP) (55 mg, 0.45 mmol) and triethylamine (607mg, 6.0 mmol) were added and the mixture was stirred for 15 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, 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 an amino bound silica gel chromatography column and eluted with methylene dichloride/methanol=100/1 to furnish 350 mg (58% yield) of the title compound as a white solid.
