실험 절차

The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-5-fluoro-pyridine (103 mg, 0.59 mmol) and 2-but-3-ynyl-benzo[d]thiazole (110 mg, 0.59 mmol, Example 35(A)). The crude residue was purified by flash chromatography (cyclohexane/AcOEt 4:1) to yield 78 mg (0.28 mmol, 47%) of 2-(4-(5-fluoropyridin-2-yl)but-3-ynyl)benzo[d]thiazole as a white solid.
