実験手順

In a round bottomed flask containing 2-hydroxymethyl-imidazo[1,2-a]pyridine (800 mg, 5.4 mmol) in DCM (8 mL), was added at R.T. thionyl chloride (1.96 mL, 27 mmol). The solution became clear and 10 min later, a precipitated was formed. The reaction mixture was stirred at R.T. for 2 hours and the solvent was removed under reduced pressure to afford 1.10 g of a brownish solid as the chlorhydrate form of 2-(chloromethyl)-imidazo[1,2-a]pyridine (Yield: 100%).
