Procedure

The title compound was prepared in accordance with the general method of Example 190(F), from 2-bromo-6-(fluoromethyl)pyridine (266 mg, 1.40 mmol) and 2-(but-3-ynyl)benzo[d]thiazole (compound 35(A), 260 mg, 1.40 mmol). The crude residue was purified over silicagel chromatography (prepacked 25 g silicagel column, Cyclohexane/AcOEt: from 100/0 to 80/20 as eluent) to afford 160 mg of 2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)benzo[d]thiazole (Yield: 38%) as a beige powder (Mp=74-76° C.).
