The title compound, C15H18ClN5O2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules, the isoxazolidine rings have an envelope conformation with the O atoms at the flap positions. Each mol-ecule has three stereogenic centres with configurations 2(S), 3(S) and 4(R), confirmed by resonant scattering. Their conformations are significantly different, for example in mol-ecule A the phenyl ring is inclined to the triazole ring by 32.5 (2)°, while in mol-ecule B the corresponding dihedral angle is 10.7 (2)°. In the crystal, the A and B mol-ecules are linked via an N-H⋯O and a C-H⋯O hydrogen bond. These units are linked by C-H⋯O and C-H⋯N hydrogen bonds, forming slabs parallel to the ab plane. There are C-H⋯π inter-actions present within the slabs.
