반응 단계
A mixture of 1H-indole-3-carbonitrile (0.1 g), 2-bromoisonicotinic acid ethyl ester (0.16 g), potassium phosphate (0.27 g), (1R,2R)-(−)-N,N′-dimethylcyclohexane-1,2-diamine (0.017 g), copper iodide (0.006 g) and toluene (0.7 mL) was stirred at 110° C. for 38 hours. The insoluble material was removed by filtration, and this filtrate was concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: ethyl acetate/n-hexane=10/90 to 66/34) to give the title compound (0.061 g).
