4-Bromo-2-(fluoromethyl)thiazole → 6-Fluoro-2-(4-(2-(fluoromethyl)thiazol-4-yl)but-3-ynyl)-imidazo[1,2-a]pyridine

Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 190(F), from 4-bromo-2-(fluoromethyl)thiazole (84 mg, 0.43 mmol) and 2-(but-3-ynyl)-6-fluoro-imidazo[1,2-a]pyridine (compound 223(E), 80 mg, 0.43 mmol). The crude residue was purified over C18 chromatography (prepacked 35 g silicagel column, H2O/CH3CN: from 100/0 to 80/20 as eluent) to afford 65 mg of 6-fluoro-2-(4-(2-(fluoromethyl)thiazol-4-yl)but-3-ynyl)-imidazo[1,2-a]pyridine (Yield: 47%) as a beige powder (Mp=82-84° C.).
