Versuchsvorschrift

To a stirred solution of N-(4-chlorophenyl)-2-(2-(2-oxo-1,2,3,4-tetrahydroquinolin-6-yloxy)acetyl)hydrazinecarbothioamide (0.2 g, 0.49 mmol) in dry DMF (10 mL) at room temperature, EDC HCl (0.189 g, 0.98 mmol) and TEA (0.148 g 1.4 6 mmol) were added. The reaction was stirred at room temperature overnight and monitored by LCMS. The solvent was removed under vacuum and then water (20 mL) was added to the residue. The solid which formed was filtered, dried, and the crude product (0.15 g) was recrystallized in a mixture of ethanol/ACN to afford 6-((5-(4-chlorophenylamino)-1,3,4-oxadiazol-2-yl)methoxy)-3,4-dihydroquinolin-2(1H)-one (70 mg, 38%) as an off white solid. 1H NMR: 400 MHZ, DMSO-d6: δ 2.41 (t, J=7.20 Hz, 2H), 2.85 (t, J=8.00 Hz, 2H), 5.23 (s, 2H), 6.80 (d, J=8.40 Hz, 1H), 6.87 (dd, J=2.80, 8.40 Hz, 1H), 6.94 (d, J=2.40 Hz, 1H), 7.42 (dd, J=2.00, 6.80 Hz, 2H), 7.58 (dd, J=2.40, 6.80 Hz, 2H), 9.96 (s, 1H), 10.77 (s, 1H). LCMS: RT 1.50 min, LCMS (ES-API), m/z 371.0 (M+H).
