実験手順

A mixture of (−)-1-(6-(2,2,2-trifluoroethoxy)pyridin-3-yl)ethanamine hydrochloride (1.50 g, 5.12 mmol, Amine-1, single enantiomer), 2-acetamidoisonicotinic acid (1.01 g, 5.63 mmol), HBTU (2.33 g, 6.14 mmol) and triethylamine (3.57 mL, 25.6 mmol) in dichloromethane (51 mL) is stirred at room temperature for 15 hours. The reaction mixture is poured into water (50 mL) and extracted with dichloromethane (50 mL). The organic layer is dried over sodium sulfate and concentrated under reduced pressure. The residue is recrystallized from ethyl acetate to give 1.30 g (66% yield) of the title compound as a white solid.
