Abstract: The title compound, C₁₄H₁₀Cl₂N₂O·0.5C₃H₆O, was synthesized by the reaction of 5-chloro-N-(4-chlorophenyl)-2-nitrobenzylamine with triphosgene, induced by a low-valent titanium reagent (TiCl₄/Zn). The dihydroquinazoline ring exhibits a boat conformation. N-HO hydrogen bonds form centrosymmetric dimers. There are also some weak C-HO interactions.
