Alkyl- and arylamination of 3-hydroxy-4-carbethoxy-5-methylthiophene

N-Alkylaminothiophene derivatives were obtained by the reaction of 3-hydroxy-4-carbethoxy-5-methylthiophene with alkylammonium acetates, while N-arylaminothiophene derivatives were obtained by the reaction of the same thiophene derivative with aromatic amines in the presence of catalytic amounts of iodine.Translated from Khimiya Geterotsilicheskikh Soedinenii, No. 12, pp. 1602–1604, December, 1970.
