The independent components of compound (II)

, showing the atom-labelling scheme and the N—H⋯O hydrogen bond (dashed line) within the selected asymmetric unit. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. The atoms bonded to atom N3 are disordered; see Comment for discussion.
