Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-(but-3-ynyl)-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one (70 mg, 0.37 mmol, Example 39(A)) and 2-bromo-6-(fluoromethyl)pyridine (78 mg, 0.41 mmol, Example 190(E)). The crude residue was purified by flash chromatography (DCM/MeOH 98:2) to yield 20 mg (67 μmol, 18%) of 2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one as an orange solid (M.P.=106-107° C.).
