实验过程
Carbonyl diimidazole (CDI) (52.0 mg, 0.32 mmol) was added to a stirred solution of 2-(1-(tert-butoxycarbonyl)azetidin-3-yl)acetic acid (69.0 mg, 0.32 mmol) in NMP (1.0 mL). After 20 minutes, N-(5-(N′-hydroxycarbamimidoyl)-2-methylphenyl)imidazo[1,2-a]pyridine-3-carboxamide (9) (49.5 mg, 0.16 mmol) was added in one portion and the resulting solution was stirred for 30 minutes before it was heated at 125° C. for 15 minutes in a microwave reactor. The reaction mixture was added dropwise to water (20 mL) with stirring. The precipitate was filtered and dried to give tert-butyl 3-((3-(3-(imidazo[1,2-a]pyridine-3-carboxamido)-4-methylphenyl)-1,2,4-oxadiazol-5-yl)methyl)azetidine-1-carboxylate (54). MS m/z 489.2 (M+1)+.
