An NH2CN-promoted convergent integration of three self-sorting domino sequences is described for the construction of 6-iodo-3-methylthioimidazo[1,2-a]pyridines from aryl methyl ketones and 2-aminopyridines. This strategy allows the construction of an imidazo[1,2-a]pyridine ring along with methylthiolation at C-3 and iodination at C-6. Preliminary mechanistic studies indicate that this process terminates at the iodination stage without Kornblum oxidation in the presence of I2 and DMSO.

In the title mol­ecule, C24H28N6O2S2, the dihedral angle between the aromatic ring planes is 42.2 (1)°. In the crystal structure, the hydr­oxy groups are involved in O—H⋯S hydrogen bonding, which links the mol­ecules into corrugated layers propagating parallel to the bc plane.

The mol­ecule of the title compound, C11H19N5O4, contains three fused rings, namely two nearly planar imidazole rings and one non‐planar triazine ring. The latter ring displays a chair conformation. Two hydroxy­lmethyl­ene groups are linked to two N atoms from separate rings of the glycoluril system.
