The synthesis of folic acid from guanidine hydrochloride.

The reaction between guanidine hydrochloride and ethyl cyanoacetate yields 2,4-diamino-6-hydroxypyrimidine, a crucial intermediate in the synthesis of folic acid, an essential precursor in the production of anti-anemia medication. This compound serves as the precursor to folate and plays a pivotal role in cellular growth, repair, and DNA synthesis in the human body. Therefore, the synthesis of 2,4-diamino-6-hydroxypyrimidine from guanidine hydrochloride and ethyl cyanoacetate provides a vital route and raw material for the production of folic acid, contributing significantly to pharmaceutical manufacturing aimed at combating anemia.
