12. Dextrorotatory dimaleate of methyl 2-[2-[4-[(4-chlorophenyl)phenylmethyl]-1-piperazinyl]ethoxy]acetate. 14.3 g (0.05 mole) of dextrorotatory (+)-1-[(4-chlorophenyl)phenylmethyl]piperazine (prepared in Example 4.2), 8.4 g (0.055 mole) of methyl (2-chloroethoxy)acetate, 11.7 g (0.11 mole) of anhydrous sodium carbonate and 0.332 g (0.002 mole) of potassium iodide are suspended in 14.3 ml of toluene. The suspension is heated with stirring for 17 hours at reflux temperature. A further 1.52 g (0.01 mole) of methyl (2-chloroethoxy)acetate are added and the suspension is further heated with stirring for 3 hours at reflux temperature, then cooled to ambient temperature and filtered. The solids are washed with 50 ml of toluene and the filtrate and the washing solvent are combined. The toluene is evaporated at 50 C. under reduced pressure in a rotating evaporator. 22.8 g of a brown oil are obtained and are taken up in 45 ml of dichloromethane. The solution is purified by chromatography (silica column (15 to 40 mum) 1 kg; eluent: pure dichloromethane gradually diluted with methanol up to a maximum of 2% of methanol (v/v)). 11.1 g of methyl 2-[2-[4-[(4-chlorophenyl)phenylmethyl]-1-piperazinyl]ethoxy]acetate in the form of an oil are obtained. Yield: 55.1%., 303-26-4
303-26-4 1-((4-Chlorophenyl)(phenyl)methyl)piperazine 9340, apiperazines compound, is more and more widely used in various fields.
