YieldReaction ConditionsOperation in experiment
456 g With pyridine; phosphorus pentachloride In methanol; dichloromethane at -30 - 5℃; for 4 h; CH2Cl2 (3L), PCl5 (374.4g) were added to 10L of the reaction flask, the temperature was stirred at room temperature down to about 0 ° C, pyridine (200mL) was slowly added dropwise to control the dropping rate,So that the internal temperature should not exceed 5 . The reaction was continued after 1h cooled to -5 , GCLE was added in portions(7Phenylacetamide-3-chloromethyl cephalanacrylate p-methoxybenzyl ester, 584.4g), controlling the internal temperature between -5 to 0 , the reaction was continued for 3h. Rapid cooling to -30 , the beginning slowly dropping methanol (1500mL), continue to -30 for 1h. The temperature was raised to -10 ° C, and 1500 mL of water was added dropwise. The temperature was controlled to -10 to 0 ° C for 1 hour. Finally, 1500mL of water was added once more and the mixture was stirred for 5min. The reaction solution was poured into a beaker with a lower mouth and was allowed to stand for delamination. The organic phase was taken off and a small amount of CH2Cl2 was added to the aqueous phase. The combined organic phases were dried over anhydrous sodium sulfate 1000g) dried,Suction filtration, the filter cake was washed with a small amount of CH2Cl2, the filtrate was added dropwise to isopropyl ether (12L) and stirred overnight. The next day, suction filtration, the filter cake was washed with a small amount of isopropyl ether, pale yellow solid, scraped the material, dried in vacuo overnight to give the product 456g.
