Procedure

0.995 g of terphthalic acid monomethyl ester chloride and 0.756 g of methyl 4-(methylamino)-benzoate were dissolved in 25 ml of acetone and treated with 0.691 g of anhydrous potassium carbonate. The reaction mixture was stirred at room temperature for 30 hours and was evaporated. The residue was treated with water and the crystals were filtered off yielding N-(4-methoxycarbonyl-phenyl)-N-methyl-terephthalamic acid methyl ester in the form of colourless crystals, MS: m/z 327 (M+).
