The asymmetric unit of the title compound, C~22~H~29~N~3~O~5~S, contains two independent molecules, __A__ and __B__, which differ slightly in the orientation of the ethyl and tosyl groups with respect to the attached pyrrolidine ring, as evidenced by the relevant torsion angles. In both molecules, t
