Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 190(F), from 2-bromopyridine (948 mg, 6.0 mmol) and 5-chloropent-1-yne (620 mg, 6.0 mmol). The crude residue was purified over silicagel chromatography (prepacked 25 g silicagel column, Cyclohexane/AcOEt: from 100/0 to 80/20 as eluent) to afford 655 mg of 2-(5-chloropent-1-ynyl)pyridine as a yellow oil (Yield: 61%).
