A mixture of 2-chloro-6-hydroxyquinoxaline (52 mg, 288 μmol), 3-[-4-(2-chloroethyl)-1-piperidinyl]-6-methylpyridazine (76 mg, 317 mmol), potassium iodide (53 mg, 317 mmol) and potassium carbonate (199 mg, 1.44 mmol) in anhydrous dimethylformamide (2 ml) was heated at 90° under an Argon atmosphere for 2 days. Tlc (silica; ethyl acetate) showed new polar material. Removal of the solvent under high vacuum and then chromatography on silica (5 g; eluent: 30% hexane in ethyl acetate) gave the product as a white solid 68 mg (61%).
