Reaction Steps

To a solution of 4-phenyl-1H-pyrrole-3-carbonitrile (0.1 g) in toluene (0.70 mL) were added 2-bromo-isonicotinic acid ethyl ester (0.19 g), potassium phosphate (0.31 g), (1R,2R)-(−)-N,N′-dimethylcyclohexane-1,2-diamine (0.02 g) and copper iodide (0.007 g) at room temperature, and this mixture was stirred at 110° C. for 24 hours. The insoluble material was removed by filtration through Celite, and this filtrate was concentrated. This obtained residue was purified by column chromatography on silica gel (eluent: ethyl acetate/n-hexane=10/90-66/34) to give the title compound (0.066 g).
