Procedure
The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (220 mg, 1.39 mmol) and 2-but-3-ynyl-5-fluoro-benzo[d]thiazole (286 mg, 1.39 mmol). The crude residue was purified by flash chromatography (DCM/MeOH 99:1 to 98:2) to yield 38 mg-(0.13 mmol, 100%) of 5-fluoro-2-(4-pyridin-2-yl)but 3-ynyl)benzo[d]thiazole as an orange solid.
