N-tert-Butyl-N′-(5,7-di­methyl-1,8-naphthyridin-2-yl)­urea

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