실험 절차

To a solution of N,N-dimethylethylenediamine (160 mg) in acetonitrile (5 ml)/THF (10 ml) were added 6-(4-biphenylylmethoxy)nicotinic acid (450 mg), WSC (340 mg), HOBt (230 mg), and triethylamine (0.7 ml) at room temperature. After stirring at room temperature for 12 hr, the reaction mixture was diluted with 10% aqueous potassium carbonates and extracted with ethyl acetate/THF. The organic layer was washed with water and saturated aqueous sodium chloride, dried, and concentrated. The residue was purified by alumina column chromatography (eluent; THF) and recrystallized from ethyl acetate/diisopropyl ether to obtain the titled compound (400 mg).
