【 摘 要 】

There are two mol­ecules in the asymmetric unit of the title compound, C11H16N2O. The pyridine rings and amide groups overlap almost perfectly (r.m.s. overlay fit = 0.053 Å), but the tertiary butyl groups have different orientations: in one mol­ecule, one of the methyl C atoms is syn to the amide O atom [O—C—C—C = −0.8 (3)°] and in the other the equivalent torsion angle is 31.0 (2)°. In the crystal, the two independent mol­ecules are linked by a pair of N—H⋯N hydrogen bonds in the form of an R22(8) loop to form a dimer. A C—H⋯O inter­action connects the dimers into [100] chains.
