New route to 2-arylthieno[2,3-d]pyrimidin-4(3H)-ones and isolation of the unoxidized intermediates

A new route to the synthesis of 2-arylthieno[2,3-d]pyrimidin-4(3H)-ones has been developed through heterocyclization of 2-amino-4,5-dimethylthiophene-3- carboxamide with aromatic aldehydes in boiling glacial acetic acid followed by air oxidation. The unox

Synthesis of some new 2-arylthieno[2,3-d]pyrimidin-4(3H)-one derivatives

Some new derivatives of 2-arylthieno[2,3-d]pyrimidin-4(3H)-ones have been prepared through a condensation reaction of 2-amino-4,5-dimethylthiophene-3- carboxamide with aroyl halides in boiling pyridine followed by cyclisation with 10% NaOH.
