実験手順

To a solution of 3-[4-(2-heptylamino-ethyl)-phenyl]-2,2-dimethyl-propionic acid (23 mg, 0.072 mmol), and N,N-diisopropylethylamine (0.152 mmol, 0.0264 mL) dissolved in toluene (2 mL) was added 2,4-difluorophenylisocyanate (0.0796 mmol, 0.0094 mL). The mixture was allowed to stir at room temperature for 72 hours, then was poured over 1 M HCl (5 mL). The aqueous layer was isolated and extracted with diethyl ether (2×). The organic layers were combined, washed with 2 M HCl (2×), brine (2×), dried over anhydrous sodium sulfate, and concentrated to give a clear film. The crude product was chromatographed on silica gel (Merck silica gel 60, art#9385-3) eluting with 5% methanol/methylene chloride to give 3-(4-{2-[3-(2,4-difluoro-phenyl)-1-heptyl-ureido]-ethyl}-phenyl)-2,2-dimethyl-propionic acid as a clear film (18.5 mg, 54%).
