Reaction Steps

(3-(3-(3-(Imidazo[1,2-a]pyridine-3-carboxamido)-4-methylphenyl)-1,2,4-oxadiazol-5-yl)oxetan-3-yl)carbamate (46) (29.5 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-(3-aminooxetan-3-yl)-1,2,4-oxadiazol-3-yl)-2-methylphenyl)imidazo[1,2-a]pyridine-3-carboxamide (47) as a TFA salt which was used without further purification. MS m/z 391.1 (M+1)+.
