摘要：2-[(N-ethylamino)methyl]-4-nitrophenol, as timing group, was synthesized from p-nitrophenol. An intermediate was prepared from 2-[(N-ethylamino)methyl]-4-nitrophenol and the coupler group through six steps. Reaction of S, S'-carbonyldi-l-enthyl-5-mercaptotetrazole and S,S'-carbonyldi-1-phenyl-5-mercaptotetrazole with the intermediate yield two DIAR (development inhibitor archimeric releasing) couplers. Their structures were characterized by 1-NMR (nuclear magnetic resonance), IR (infrared spectrum) and MS (mass spectrum).
