In the crystal of the title compound, C26H31N3O2, pairs of N-HO hydrogen bonds link molecules, forming inversion dimers, which enclose an R22(20) ring motif. One N atom does not form hydrogen bonds and lies in a hydrophobic pocket with closest intermolecular contacts of 4.196 (2) and 4.262 (2) Å.
For the synthesis of the title compound, and a discussion of the use of the three-component Ugi reaction to synthesize amidines, see: Saha et al. (2013).
