Procedure

First, 0.55 g of 4-iodobenzyl bromide was dissolved in 10 ml of N,N-dimethylformamide, to which the suspension of 0.11 g of sodium hydride (60% in oil) and 0.30 g of (3,3,3-trifluoropropyl)malononitrile in 5 ml of N,N-dimethylformamide was added dropwise, while stirring under ice cooling. After stirring for 4 hours at 0° C., 10% hydrochloric acid was added to the reaction mixture at room temperature, which was extracted with ethyl acetate. The organic layer was successively washed with water, a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.16 g of 2-(4-iodobenzyl)-2-(3,3,3-trifluoropropyl)malononitrile (the present compound (26)).
