Procedure

The title compound was prepared in accordance with the general method of Example 192(A), from 2-iodopyridine (50 mg, 0.2 mmol) and 1-(but-3-ynyl)pyridin-2(1H)-one (33 mg, 0.2 mmol). The crude residue was purified over silicagel chromatography (prepacked 10 g silicagel column, DCM/MeOH: from 100/0 to 97/3 as eluent) to afford 10 mg of 1-(4-(pyridin-2-yl)but-3-ynyl)pyridin-2(1H)-one as a yellow oil (Yield: 20%).
