The title compound was prepared in accordance with the general method of Example 1, from 2-(but-3-ynyl)-8-chloro-imidazo[1,2-a]pyridine (500 mg, 2.44 mmol, Example 255(B)) and 2-bromo-6-(fluoromethyl)pyridine (487 mg, 2.57 mmol, Example 190(E)). The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 420 mg (1.34 mmol, 55%) of 8-chloro-2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)-imidazo[1,2-a]pyridine as a slightly yellow solid (M.P.=73-74.5° C.).
