Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-bromo-4-methylthiazole (100 mg, 0.56 mmol) and 2-(but-3-ynyl)-2H-benzo[d][1,2,3]triazole (96 mg, 0.56 mmol, Example 109(D)). The crude residue was purified by flash chromatography (cyclohexane/AcOEt 4:1) to yield 40 mg (0.15 mmol, 27%) of 2-(4-(4-methylthiazol-2-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole as a white solid (M.P.=78-80° C.).
