Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 5.8 g of 4-chlorobenzyl cyanide, 10 g of ethyl 2-trifluoromethylbenzoate and 2.9 g of sodium ethylate were added to 100 ml of toluene and then reacted for 8 hours under reflux. The reaction mixture was returned to room temperature and extracted by an addition of 200 ml of water. The aqueous phase was adjusted to pH 6 to 7 with 6N hydrochloric acid and then extracted by an addition of 400 ml of methylene chloride. The organic layer was washed with water and a saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 6.3 g of the desired product. The NMR spectrum data of this product were the same as in Reference Preparation Example 3. reacted for 8 hours under reflux was returned to room temperature extracted by an addition of 200 ml of water extracted by an addition of 400 ml of methylene chloride The organic layer was washed with water a saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate The solvent was distilled off under reduced pressure
