Procedure

The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (193 mg, 1.22 mmol) and 2-but-3-ynyl-4-methyl-benzo[d]thiazole (246 mg, 1.22 mmol). The crude residue was purified by flash chromatography DCM/MeOH 99:1 to 98:2) to yield 86 mg (0.31 mmol, 25%) of 4-methyl-2-(4-pyridin-2-yl)but-3-ynyl)benzo[d]thiazole as a brown oil.

Workup

  1. customThe crude residue was purified by flash chromatography DCM/MeOH 99:1 to 98:2)
