5-Fluoro-1,2,3,4-tetrahydroquinoline → HCID 68194300, compound

Participants

Reaction Steps

To a solution of methyl 3-chloro-2-oxo-1,2-dihydroquinoxaline-6-carboxylate (1.0 g, 4.19 mmol) in NMP (10.0 mL) was added 5-fluoro-1,2,3,4-tetrahydroquinoline (1.5 g, 9.92 mmol) with stifling for 1 h at 150° C. in an oil bath. The reaction mixture was cooled to room temperature, precipitated with water (100 mL). The solids were collected by filtration and dried in an oven under reduced pressure to afford methyl 3-(5-fluoro-1,2,3,4-tetrahydroquinolin-1-yl)-2-oxo-1,2-dihydroquinoxaline-6-carboxylate as a gray solid (1.0 g, crude).
