Reaction Steps

To a stirring suspension of tert-butyl (3-(3-(imidazo[1,2-a]pyridine-3-carboxamido)-4-methylphenyl)-1,2,4-oxadiazol-5-yl)methyl(methyl)carbamate (F54) (90 mg, 0.195 mmol) in acetonitrile (1 mL) was added 4N HCl in dioxane (1 mL) and water (0.5 mL). The reaction mixture was stirred at room temperature for 45 minutes. Then, the solvent was concentrated and the crude product was dried under high vacuum. The crude product N-(5-(5-(aminomethyl)-1,2,4-oxadiazol-3-yl)-2-methylphenyl)imidazo[1,2-a]pyridine-3-carboxamide (26) was used in the next step without further purification. 1H NMR (400 MHz, d6-DMSO) δ 10.04 (s, 1 H), 9.46-9.44 (m, 1 H), 8.74 (s, 2 H), 8.63 (s, 1 H), 8.15 (d, J=2.0 Hz, 1 H), 7.86-7.80 (m, 2 H), 7.59-7.54 (m, 1 H), 7.55 (d, J=8.4 Hz, 1 H), 7.23-7.20 (m, 1 H), 4.62 (s, 2 H), 2.39 (s, 3 H). MS m/z 349.4 (M+1)+.
