The title compound, C15H20N4O, has been synthesized as an AADD recognition
unit for quadruple hydrogen bonds. All non-H atoms of the molecule apart fr
om two methyl groups of the tert-butyl group lie in a common plane. An intr
amolecular hydrogen bond is formed connecting two N atoms. In the solid sta
te, the title compound crystallizes as a centrosymmetric dimer connected by
N-H . . .O=C interactions with an N . . .O distance of 2.824 (2) Angstrom.
