A solution of 2-amino-2-(4-chlorophenoxymethyl)-propionitrile (0.5 g, 0.24 mmol), 4-chlorophenyl-methylsulfonyl chloride (0.46 g, 2.4 mmol) and diazabicyclooctane (0.6 g, 2.4 mmol) in anhydrous tetrahydrofuran (20 ml) is stirred for about 16 hours. The reaction mixture is diluted with ethyl acetate and washed with brine. The organic phase is dried over magnesium sulfate and the raw product received as the residue is purified by flash chromato-graphy (eluent: ethyl acetate/hexanes 1:3) to give the 2-(4-chlorophenoxy-methyl)-2-(4-chlorophenyl-methylsulfonyl)-propionitrile in form of colorless crystals, m.p. 119-120° C.
