Abstract

NEW MATERIAL:A 2-alkoxy-5-haloterephthalamic acid-1-alkyl ester expressed by formula I (R is alkyl; X is halogen).
EXAMPLE: 2-Methoxy-5-chloroterephthalamic acid-1-methylester.
USE: An intermediate for the synthesis of medicines, e.g. and intermediate of a benzamide derivative having analgesic, sedative, neuroleptic effects, etc.
PROCESS: A 2-alkoxy-5-haloterephthalic acid-1-alkyl ester-4-chloride of formula II is reacted with any one of gaseous or aqueous ammonia, or an ammonium salt, e.g. ammonium carbonate or ammonium secondary phosphate, in a solvent, e.g. acetone or benzene, preferably at 0W10°C, for 1W2hr, to give a compound of formula I.
