Procedure

The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (20 mg, 0.13 mmol) and 2-but-3-ynyl-7-chloro-4-methyl-benzo[d]thiazole (30 mg, 0.13 mmol). The crude residue was purified by flash chromatography (DCM/MeOH 99:1 to 98:2) to yield 2.9 mg (9.3 μmol, 7%) of 7-chloro-4-methyl-2-(4-(pyridin-2-yl)but-3-ynyl)benzo[d]thiazole as a brown oil.
