Into a glass flask having an internal volume of 300 mL, equipped with a stirring apparatus, a thermometer, a reflux condenser and a Dean-Stark apparatus, 11.6 g (106.6 mmol) of 3-cyclopropyl-3-oxopropanenitrile, 31.0 g (96.9 mmol) of 2-amino-4′-fluorobenzophenone methanesulfonate having a purity of 97.3% and 121 mL of toluene were put in an atmosphere of nitrogen, and reaction was carried out under 0.04 MPa at 80° C. for 2 hours while distilling off the formed water. After completion of the reaction, the reaction liquid was cooled to room temperature, 60 mL of water and 13.3 mL (106.4 mmol) of a 8 mol/L sodium hydroxide aqueous solution were added thereto to make the reaction liquid basic, followed by liquid separation, and the obtained organic layer was analyzed by high performance liquid chromatography (absolute quantitative analysis), whereupon 27.9 g (yield: 99%) of 2-cyclopropyl-4-(4′-fluorophenyl)quinoline-3-carbonitrile was formed.
