The title compound, C10H12N2S, does not contain any strong hydrogen-bond donors but two long C-H⋯N contacts are observed in the crystal structure, with the most linear inter-action linking mol-ecules along [010]. The ellipsoids of the tert-butyl group indicate large librational motion.
Keywords: 1,3-thiazolo[4,5-b]pyridine; C—H⋯N contacts; crystal structure.
