Yield:78649-41-9 95%
Reaction Conditions:
with sodium hydroxide in N,N-dimethyl acetamide at 10 - 60; for 16 h;
Steps:
6 Synthesis of Iomeprole
Prepared N,N-bis(2,3-dihydroxypropyl)-5-(2-hydroxyacetamido)-2,4,6-triiodoisophthalamide 20 g (0.026 mol) in a reactor and 60 g of N,N-dimethylacetamide was added, followed by heating and stirring at 60 °C to dissolve.1.3 g (0.033 mol) of caustic soda was added to the reactor and stirred to dissolve. The reactor was cooled to 10 °C or less, and 4.5 g (0.032 mol) of iodomethane was added to the reactor, followed by stirring at 25 °C for 14 to 16 hours. After confirming the completion of the reaction, acetic acid was added to neutralize the reaction solution.The solvent was removed through concentration under reduced pressure at 60 to 65 °C and 60 g of ethanol was added to crystallize. The wet body was obtained by filtration and dried under reduced pressure in an oven at 60 °C for 12 hours to obtain iomeprol (yield 95%, purity 99.8%).
