실험 절차
Methyl 6-(2-((dimethylamino)methyl)imidazo[1,2-a]pyridin-6-yl)-5-ethyl-2-methoxynicotinate (100.6 mg, 0.27 mmol) was heated with 6 M HCl (1.50 mL) at 80° C. for 3 h. HCl was removed under reduced pressure affording 6-(2-((dimethylamino)methyl)imidazo[1,2-a]pyridin-6-yl)-5-ethyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid (113.3 mg) as dihydrochloride salt in 99% overall yield.
