Publication Abstract

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 A˚ ), 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 R2 2 (8) loop to form a dimer. A C—H…O interaction connects the dimers into [100] chains.
