Procedure
A mixed solution containing 10 g of cyclohexyl 2-(4-cyanophenylthio)acetate (36.3 mmol), 0.8 g of AlBr3 and 50 g of trichloroacetonitrile was bubbled with dry HCl at room temperature. The process of reaction was checked by TLC. The reaction product was formed gradually with the lapse of time while precipitation was formed. After 24 hours, the reaction mixture was quenched and extracted with 500 mL of chloroform. The resultant product was washed with deionized water and dried over anhydrous magnesium sulfate. Volatile substances were removed from the dried product under vacuum and the target product was separated by column chromatography using hexane/ethyl acetate (3/1) as eluent (yield: 89%). Then, the product was subjected to structural analysis by NMR, FT-IR and UV-Vis. spectrophotometers.
