Versuchsvorschrift

Step R1-5: To a suspension of 2-oxo-1,2,3,4-tetrahydroquinoline-7-carbaldehyde (135 g) in CHCl3 (1.4 L) were added 3-methoxy-N-(piperidin-4-yl)benzamide (190 g) and AcOH (45 mL) at room temperature. The mixture was stirred at room temperature for 2 hours. After cooling to 0° C., NaBH(OAc)3 was added portionwise. The mixture was stirred at room temperature for 19 hours. After cooling to 0° C., 8 M aqueous NaOH (0.5 L) and water (0.5 L) were added to the reaction mixture. The organic layer was separated, washed with water and brine, dried over MgSO4 and concentrated to obtain a colorless solid. The solid was suspended in EtOAc (3.0 L) and the mixture was refluxed for 1 hour and cooled to room temperature. The precipitate was filtrated to obtain a colorless solid. The solid was suspended again in EtOAc (2.4 L), and the mixture was refluxed for 1 hour and cooled to room temperature. The precipitate was filtrated to obtain the titled compound as a colorless solid (229 g).
