A solution of 2-(4-chlorophenyl)-cyclohexanone (100 g, 0.48 mol) in N,N-dimethylformamide (0.5 L) was added slowly to a mixture of sodium hydride (13.8 g, 0.78 mol) in N,N-dimethylformamide (0.2 L), the temperature being kept below 40° C. The reaction mixture was stirred at 20-25° C. for 1.5 h when a precipitate was formed. The mixture was diluted with N,N-dimethylformamide (0.2 L), and thereafter, a solution of chloroacetonitrile (43.0 g, 0.57 mol) in N,N-dimethylformamide (0.1 L) was slowly added with cooling over 0.5 h, the temperature being kept below 25° C. The mixture was stirred for 18 h, and then, ethanol (50 mL) was slowly added. The mixture was stirred for 0.5 h and then poured onto ice-water.
