Abstract
4-[4-(Ethoxycarbonyl)piperazin-1-yl]benzoic acid (EPBA) is the product of a reaction between ethyl 1-piperazinecarboxylate and 4-fluorobenzoic acid. The conformation of the two independent molecules (A and B) in the asymmetric unit is similar. The piperazine ring adopts a chair conformation in both molecules. The dihedral angles formed by the four approximately planar C atoms of the piperazine ring and the benzene ring is 30.8 (5)° in molecule A and 30.6 (5)% in molecule B.
