2-Bromopyridine → 2-(4-(4-(4-fluorophenyl)-2H-1,2,3-triazol-2-yl)but-1-ynyl)pyridine

Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 2-(but-3-ynyl)-4-(4-fluorophenyl)-2H-1,2,3-triazole (150 mg, 0.70 mmol, Example 254(B)) and 2-bromopyridine (122 mg, 0.77 mmol). The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 84 mg (0.29 mmol, 41%) of 2-(4-(4-(4-fluorophenyl)-2H-1,2,3-triazol-2-yl)but-1-ynyl)pyridine as a yellow solid (M.P.=83.5-84.5° C.).
