A mixture of the ethyl (RS)-(3-amino-5-ethyl-phenyl)-(4-cyano-phenylamino)-acetate (500 mg, 1.55 mmol) obtained in Example 223.4, bis-(2-chloroethylamine) hydrochloride (276 mg, 1.55 mmol) and chlorobenzene (5 ml) was heated under reflux for 18 h. The reaction mixture was concentrated and the residue was purified by chromatography (SiO2, CH2Cl2MeOH 9:1). There were obtained 385 mg (63%) of ethyl (RS)-(4-cyano-phenylamino)-(3-ethyl-5-piperazin-1-yl-phenyl)-acetate as a brownish solid; MS: 393 ([M+H]+).
