実験手順

The title compound was prepared in accordance with the general method of Example 199(A), from 2-bromo-6-(fluoromethyl)pyridine (compound 190(E), 3.50 g, 18 mmol) and 3-butyn-1-ol (1.3 g, 18 mmol). The crude residue was purified over silicagel chromatography (prepacked 85 g silicagel column, DCM/MeOH: from 100/0 to 97/3 as eluent) to afford 2.60 g of 4-(6-(fluoromethyl)pyridin-2-yl)but-3-yn-1-ol as an orange solid (Yield: 79%).
