실험 절차

To a solution of ethyl 6-cyanoimidazo[1,2-a]pyridine-3-carboxylate (24q) (265 mg, 1.23 mmol) and 2-methoxyacetohydrazide (193 mg, 1.85 mmol) in 2-ethoxyethanol (5 mL) was added NaOMe (0.5 M in MeOH, 3.7 mL). The mixture was heated at 110° C. in a sealed vial overnight. The reaction mixture was purified by HPLC to give 6-(3-(methoxymethyl)-1H-1,2,4-triazol-5-yl)imidazo[1,2-a]pyridine-3-carboxylic acid (99). MS m/z 274.1 (M+1)+.
