Versuchsvorschrift
The title compound was prepared in accordance with the general method of Example 190(F), from 2-bromo-6-(fluoromethyl)pyridine (220 mg, 1.10 mol) and 2-(but-3-ynyl)-6-fluoro-imidazo[1,2-a]pyridine (220 mg, 1.14 mmol). The crude residue was purified over C18 chromatography (prepacked 35 g silicagel column, H2O/CH3CN: from 95/5 to 55/45 as eluent) to afford 155 mg of 6-fluoro-2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)H-imidazo[1,2-a]pyridine (Yield: 46%) as a white powder (Mp=140-141.8° C.).
