6-Amino-1,3-diethyl-2,4(1H,3H)-pyrimidinedione

It provides the uracil (pyrimidine) core with an amino group at C6, which is essential for amide bond formation with substituted cinnamic acid derivatives. This intermediate serves as the scaffold for further functionalization, including side-chain attachment and cyclization steps, ultimately leading to the construction of the xanthine-like structure characteristic of Istradefylline and enabling its activity as an adenosine A₂A receptor antagonist. 6-Amino-1,3-diethyl-2,4(1H,3H)-pyrimidinedione is a crucial intermediate in the synthesis of Istradefylline.
