Abstract: The title compound, C₂₃H₁₂Cl₃N₃O₂S·0.5C₄H₈O₂, was synthesized by the intermolecular [3+2]-cycloaddition of 2,6-dichlorobenzonitrile oxide and 2-(2-chlorobenzylidene)benzo[4,5]imidazo[2,1-b]thiazol-3-one. The dioxane molecule of solvation is located about a centre of inversion. A spiro junction links an isoxazoline ring and a planar benzo[4,5]imidazo[2,1-b]thiazol-3-one ring.
