Tikanga Whakaputa
Ko te waikawa Adipic me te thionyl chloride i konatunatua ki te tauwehenga taumaha o te 1: (6-10) me te refluxed mo te 20-60 h i te aroaro o te pyridine catalyst.I whakaeto te whakarewa me te whakamahana i te toenga i te 140-160 ℃ mo te 3-7 H. Ko te waikawa Thiophene-2,5-dicarboxylic i riro mai i te maimoatanga konutai hydroxide, te rerenga waikawa, te filtration, te whakaheke me te purenga.
