The title compound, C16H21FN2O3S, was obtained from the reaction between sulfonyl azide, cyclohexanone and morpholine. The bond lengths at the amidine N—C—N grouping are similar [1.326 (3) and 1.338 (3) Å], indicating significant conjugation. The cyclopentyl moiety displays disorder of one of the methylene groups into two orientations with occupancy coefficients 0.75/0.25. No shortened intermolecular contacts in the crystal are observed.
