Abstract
NEW MATERIAL:A compound of formula I (R is lower alkyl).
EXAMPLE: Methyl o-γ-monobromoacetoacetamidobenzoate.
USE: Synthetic intermediate of various chemicals. Extremely useful as a synthetic intermediate of pharmaceuticals having the activity of, e.g. antiphlogistic and analgesic agent.
PROCESS: The compound of formula I can be prepared by reacting 1mol of alkyl.o- acetoacetamidobenzoate of formula II with 1mol of bromine in an alcohol (e.g. methanol, ethanol, etc.). The reaction is carried out at ≤20°C by adding bromine slowly dropwise to the reaction system.
