実験手順

To the black liquid 5-fluoroimidazo[1,2-a]pyridine (650 mg) was added conc. hydrochloric acid (5 mL). The mixture was concentrated, which was crystallized from a mixture of ethanol, THF and ethyl acetate (10 mL:50 mL:200 mL) to afford 5-fluoroimidazo[1,2-a]pyridine monohydrochloride as a powdery product (690 mg, yield 83%).
