実験手順

To a solution of (E)-N′-hydroxy-2-((2-oxo-1,2,3,4-tetrahydroquinolin-6-yl)oxy)acetimidamide (0.1 g, 0.425 mmol) in ethyl acetate (10 mL) was added a 0.5M solution of zinc chloride (0.073 mL, 0.510 mmol) followed by N-(3,4-dichlorophenyl)cyanamide (0.080 g, 0.425 mmol) and stirred at room temperature for 12 h. Then reaction mixture was concentrated. Ethanol (10.00 mL) was added along with HCl (0.1 mL, 3.29 mmol) and the reaction mixture was heated at 80° C. for 6 h. The reaction mixture was concentrated and basified with sodium bicarbonate solution, then the resulting solid was filtered and was washed with acetonitrile to give 6-((5-((3,4-dichlorophenyl)amino)-1,2,4-oxadiazol-3-yl)methoxy)-3,4-dihydroquinolin-2(1H)-one as a white solid (12 mg, 6.8% yield). 1H NMR 400 MHz, DMSO-d6: δ 2.41 (t, J=15.20 Hz, 2H), 2.84 (t, J=15.20 Hz, 2H), 4.94 (s, 2H), 6.77-6.79 (m, 1H), 6.84-6.87 (m, 1H), 6.93 (d, J=2.80 Hz, 1H), 7.30 (s, 1H), 7.37 (s, 1H), 7.80 (s, 1H), 9.91 (s, 1H). LCMS: RT 1.963 min; LCMS (ES-API), m/z 403.0 [M−H]−.
