실험 절차

A solution of (3-(3-(imidazo[1,2-a]pyridine-3-carboxamido)-4-methylphenyl)-1,2,4-oxadiazol-5-yl)methyl methanesulfonate (44) (21.4 mg, 0.05 mmol), DIEA (13.0 mg, 0.1 mmol) and morpholine (13.0 mg, 0.15 mmol) in DMF (1 mL) was heated at 80° C. for 4 hours. The crude product was purified by preparative HPLC to yield N-(2-methyl-5-(5-(morpholinomethyl)-1,2,4-oxadiazol-3-yl)phenyl)imidazo[1,2-a]pyridine-3-carboxamide (F22). 1H NMR (400 MHz, CD2Cl2) δ 9.60 (d, J=6.8 Hz, 1H), 8.60 (d, J=1.6 Hz, 1H), 8.45 (s, 1H), 8.06 (s, 1H), 7.89 (dd, J=2.0, 8.0 Hz, 1H), 7.80 (d, J=8.8 Hz, 1H), 7.54 (m, 1H), 7.43 (d, J=8.0 Hz, 1H), 7.15 (m, 1H), 3.93 (s, 2H), 3.75 (m, 4H), 2.67 (m, 4H), 2.48 (s, 3H). MS m/z 419.2 (M+1)+. Note: if HCl salt of morpholine (0.15 mmol) was used, AgNO3 (0.15 mmol) was needed to avoid replacement of OMs group by Cl.
