To a stirred solution of 1,3,5-trichloro-2-chloromethyl-benzene (12.85 g, 58.8 mmole) in ethanol (45 ml), NaCN (3.20, 67.0 mmole) solution in water (15 ml) was added at ambient temperature. The reaction mixture was refluxed for 4 hours to complete the reaction. Ethanol was evaporated and the reaction mixture was diluted with water (50 ml). The aqueous layer was extracted with EtOAc (3×100 ml). The combined organic layer was washed with brine (30 ml) and dried over sodium sulfate. Organic layer was concentrated under vacuum to give white solid. Crude product was purified by chromatography on silica-gel column to afford 9.0 g (75.0% of theory) of (2,4,6-trichloro-phenyl)-acetonitrile
