実験手順
3-((3-(3-(Imidazo[1,2-a]pyridine-3-carboxamido)-4-methylphenyl)-1,2,4-oxadiazol-5-yl)methyl)azetidine-1-carboxylate (54) (29.3 mg, 0.06 mmol) was dissolved in TFA (0.5 mL) and stirred at room temperature for 10 minutes. Then TFA was removed under vacuum to yield crude N-(5-(5-(azetidin-3-ylmethyl)-1,2,4-oxadiazol-3-yl)-2-methylphenyl)imidazo[1,2-a]pyridine-3-carboxamide (55) which was used without further purification.
