A mixture of 4-{[2-chloro-4-(trifluoromethyl)pyrimidin-5-yl]carbonyl}morpholine (150 mg), 6-nitro-1,2,3,4-tetrahydroquinoline (136 mg), tris(dibenzylideneacetone)dipalladium(0) (14 mg), (R)-(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (19 mg), sodium tert-butoxide (98 mg), and toluene (2 mL) was stirred at 110° C. for 30 minutes under radiation with microwave. To the reaction mixture was added water and the aqueous layer was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate), and the obtained residue was solidified from a mixed solvent of hexane and ethyl acetate to obtain 1-[5-(morpholin-4-ylcarbonyl)-4-(trifluoromethyl)pyrimidin-2-yl]-6-nitro-1,2,3,4-tetrahydroquinoline (62 mg) as a yellow powder.
