1-(4,6-Di­methyl­pyrimidin-2-yl­sulfanyl)-3,3-di­methyl­butan-2-one

In the title mol­ecule, C₁₂H₁₈N₂OS, all bond lengths and angles are normal. The non-H atoms of the 4,6-di­methyl­pyrimidin-2-yl­sulfanyl moiety are coplanar. In the crystal structure, the pyrimidine rings form stacks along the c axis with a short interplanar distance of 3.35 Å, indicating the presence of π–π stacking interactions.
