Two routes to the synthesis of ethyl 6-(trifluoromethyl)-1H-indole-3-carboxylate are described. N-Amination of this key intermediate with O-(diphenylphosphinyl)hydroxylamine and subsequent reactions with aryl isocyanates, using pyridine as solvent, gave the corresponding N-aminoindole ureas 1-4 in good yields.
本文介绍了合成 6-(三氟甲基)-1H-吲哚-3-羧酸乙酯的两条途径。以吡啶为溶剂,将该关键中间体与 O-(二苯基膦酰基)羟胺进行 N-胺化,然后与芳基异氰酸酯反应,得到相应的 N-氨基吲哚脲 1-4,收率良好。
