4-Bromo-1,2-dimethyl-1H-imidazole → 4-chloro-2-(4-(1,2-dimethyl-1H-imidazol-4-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole

Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 108(C), from 4-bromo-1,2-dimethyl-1H-imidazole (85 mg, 0.49 mmol) and 2-but-3-ynyl-4-chloro-2H-benzo[d][1,2,3]triazole (100 mg, 0.49 mmol, Example 146(B)). Microwave conditions: 100° C. for 15 min. The crude residue was purified by C18 flash chromatography to yield 8.0 mg (27 mmol, 5%) of 4-chloro-2-(4-(1,2-dimethyl-1H-imidazol-4-yl)but-3-ynyl)-2H-benzo[d][1,2,3]triazole as a brown semi-solid.
