Abstract
5-Methylthieno[2,3-d]pyrimidine-6-carboxylates substituted with prop-1-en-1-yl and hexa-1,5-dien-3-yl fragments in the C-4 position of the heterocycle were obtained in Suzuki coupling reaction of potassium allyltrifluoroborate and ethyl 4-chloro-5-methylthieno[2,3-d]- pyrimidine-6-carboxylate. Further transformations of the products allowed confirming the structure and molecular geometry of the obtained compounds.
