Abstract: PURPOSE: Terephthalic acid amide derivatives are provided, which have improved antiviral activity to hepatitis B virus and no toxicity, so that they can be useful for prevention and treatment of hepatitis B. CONSTITUTION: The terephthalic acid amide derivatives containing substituted phenylpiperazine group represented by formula (1), and pharmaceutically acceptable salts thereof are provided, wherein R1 is hydrogen, halogen, C1-C3 lower alkyl, lower alkoxy or lower acyl, trifluoromethyl, amino or nitro. The method for preparing the terephthalic acid amide derivatives of formula (1) comprises the steps of: (a) reacting a compound of formula (2) with a compound of formula (3) to prepare a compound of formula (4); (b) hydrolysis of benzoic acid methylester of formula (4) to prepare a compound of formula (5); and (c) reacting the compound of formula (5) with acid chloride to prepare acid anhydride and reacting the acid anhydride with a compound of formula (6).
