Versuchsvorschrift

A solution of 0.01 mol of 2-phenoxyisobutyric acid chloride (obtained by reaction of thionyl chloride with 2-phenoxyisobutyric acid) in 100 ml of methylene chloride is introduced into an Erlenmeyer flask containing a solution of 0.01 mol of 1-benzylpiperazine in 100 ml of methylene chloride. The mixture is stirred for 5 hours at room temperature, filtered and evaporated to dryness. The residue is taken up in water, basified and extracted with chloroform. The organic phases are combined, dried and evaporated.
