Procedure

1.70 g of 1-(chloromethyl)-3-cyano-1H-indole and 1.45 g of (3,3,3-trifluoropropyl) malononitrile were dissolved in 27 ml of N,N-dimethylformamide. 2.49 g of potassium carbonate was added to the solution under ice cooling with stirring, followed by stirring at room temperature for 7 hours. Water was added to the reaction mixture, and then extracted with MTBE. The organic layer was washed with water, dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 1.48 g of [{3-cyano-1H-indole-1-yl}methyl] (3,3,3-trifluoropropyl) malononitrile (referred to as the compound of the present invention (39), hereinafter) shown by below formula.
