甲基 4-氰基丁酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 6.2 15 ml of oxalyl chloride are added dropwise at from −2 to 0° to a solution of 15 ml of DMF in 300 ml of acetonitrile, and the mixture is stirred for a further 30 minutes. 23.25 g of “FA” are added dropwise at a maximum of 0°, and, after the mixture has been stirred for 15 minutes, 29 ml of pyridine are added dropwise. Ether is added, and the mixture is subjected to conventional work-up, giving 20 g of methyl 4-cyanobutyrate (“FB”) as an oil. 23.25 g of “FA” are added dropwise at a maximum of 0° after the mixture has been stirred for 15 minutes
