Abstract
The commercially available title compound, C(25)H(23)N(3)O(2), has been known since 1993 [Nesper et al. (1993 ▶). Helv. Chim. Acta, 76, 2239-2249], but has not been structurally characterized until now. In the free ligand, the N atoms of both oxazoline rings point in opposite directions. The phenyl rings make dihedral angles of 30.56 (5) and 84.57 (3)° with the pyridine ring and 72.85 (3)° with each other.
