YieldReaction ConditionsOperation in experiment
68.4 g In a 2 L four-necked flask, 1200 mL of ethyl acetate, ethyl 2-chloro-2-[2-(4-nitrophenyl)phosphonium]acetate (60 g, 0.23 mol) was added.After stirring, completely dissolved, continue to add 5,6-dihydro-3-(4-morpholinyl)-1-[4-(2-oxo-1-piperidyl)phenyl]-2 (1H) -pyridone (61 g, 0.17 mol),Protected with nitrogen, stirred for 15 min to obtain a suspension, and dropwise added 80 mL of triethylamine.The temperature was raised to 65 C by heating, and after the reaction was kept for 8 hours, the temperature was lowered to 20 C, 72 mL of 4 mol/L hydrochloric acid was added dropwise, and the temperature was raised to 45 C after heating.After reacting for 3 hours, the temperature was lowered to 25 C, and the pH was adjusted to 6 by adding sodium hydrogen carbonate solution, and the mixture was allowed to stand, and the organic layer was washed with water (200 mL × 2).Dry over anhydrous sodium sulfate,Filtration and concentration of the filtrate to dryness afforded 68.4 g.
