How is Nicotinic acid - 7-{2-hydroxy-3-[(2-hydroxyethyl)(methyl)amino]propyl}-1,3-dimethyl-3,7-dihydro-1H-purine-2,6-dione (CAS: 437-74-1) typically synthesized?

Nicotinic acid - 7-{2-hydroxy-3-[(2-hydroxyethyl)(methyl)amino]propyl}-1,3-dimethyl-3,7-dihydro-1H-purine-2,6-dione (CAS: 437-74-1) is synthesized through a multi-step process involving the condensation of 2-hydroxyethylamine and methylamine with 7-chloro-1,3-dimethyl-3,7-dihydro-1H-purine-2,6-dione. The reaction typically requires a suitable base catalyst and is performed under mild to moderate conditions to achieve high yield and selectivity.
