Structure of Tiaramide

Abstract

The crystal of the title compound, C₁₅H₁₈ClN₃O₃S, belongs to space group P2₁/a with cell dimensions a = 12.744(5), b = 8.260(2), c = 15.513(5)Å, and β = 93.42(2)°. The final R value is 0.053. The piperadine ring is almost perpendicular to the benzothiazolyl ring. The piperadine ring adopts a chair conformation in which the acetyl and ethanol groups are equatorial. There is one intermolecular O-H…N hydrogen bond that connects two molecules around the center of symmetry into a dimer.
