실험 절차
To a solution of 2-[2-(N-methylformamido)-4-methylthiazol-5-yl]-7-methylimidazo[1,2-a]pyridine (4.87 g) in ethanol (200 ml) was added 36% hydrochloric acid (2.6 ml) and refluxed for 1.5 hours. The reaction mixture was evaporated. The residue was dissolved in water, and the aqueous mixture was adjusted to pH 8 with saturated potassium carbonate. Extraction with chloroform, and evaporation afforded 2-(2-methylamino-4-methylthiazol-5-yl)-7-methyl-imidazo[1,2-a]pyridine (3.22 g). mp 220°-221° C.
