実験手順

A mixture of (R)-3-(1-(6-chloropyrazin-2-yloxy)ethyl)aniline (160 mg, 0.64 mmol), 3-trifluoromethylbenzoic acid (183 mg, 0.96 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (246 mg, 1.28 mmol), 4-dimethylamino pyridine (4 mg, 0.032 mmol) and triethylamine (0.36 mL, 2.57 mmol) in dichloromethane (6 mL) was stirred at room temperature for 18 hours. After this time the mixture was diluted with dichloromethane (30 mL), washed successively with saturated aqueous sodium hydrogen carbonate (2×20 mL) and brine (20 mL), dried (Na2SO4) and concentrated under reduced pressure to give an orange oil which was purified by flash chromatography (silica, ethyl acetate/hexanes) to give (R)—N-(3-(1-(6-chloropyrazin-2-yloxy)ethyl)phenyl)-3-(trifluoromethyl)benzamide (110 mg, 30% over 2 steps) as a yellow foam.
