Abstract

NEW MATERIAL:A 2-methoxy-5-haloterephthalic acid-1-alkyl ester-4-chloride shown by the formula I (R is alkyl; X is halogen).
EXAMPLE: 2-Methoxy-5-chloroterephtalic acid-1-methylester-4-chloride.
USE: An intermediate for synthesizing druge effective for pain killing, sedation, neurolepsy, tension lowering of pneuma, etc.
PROCESS: A 2-methoxy-5-haloterephthalic acid-1-alkyl ester shown by the formula II is reacted with a chlorinating agent, e.g., thionyl chloride, phosphorus pentachloride, phosphorus trichloride, etc. in the presence of benzene, acetone, etc. at 50W 100°C to give a compound shown by the formula I.
