Procedure

1,1′-carbonyldiimidazole (0.18 g, 1.1 mmol) was added to a solution of the 4-hydroxy benzoic acid (0.15 g, 1.1 mmol) in absolute pyridine and the mixture was stirred at room temperature under Argon for 1 h. After that time a solution of 4-[4-(2,3-Dichloro-phenyl)-piperazin-1-yl]-but-2-enylamine (0.33 g, 1.1 mmol) in 3 ml amylene-stablized chloroform was added and the mixture was stirred overnight. All volatiles were removed in vacuo and the residue was purified by chromatography to give 0.23 g (51%) of the title compound.
