반응 단계
To a stirred solution of mono-methyl terephthalate (1 equivalent), toluene (30 ml/gm of ester) and 3 drops of DMF was added dropwise oxalyl chloride (2.0 equivalents). The reaction mixture was stirred at 45° C. for 16 hours. The solution was concentrated under reduced pressure to give the desired product as a pale yellow solid. The product was used without further purification; yield 82.0%; m.p. 50°-52° C. IR (thin film); 2970, 1775, 1720, 1430, 1400, 1280, 1105, 880 cm-1.
