How is Dimethyl 2-propyl-1H-imidazole-4,5-dicarboxylate (CAS: 124750-59-0) typically synthesized?

Dimethyl 2-propyl-1H-imidazole-4,5-dicarboxylate is synthesized through a multi-step process involving the formation of an imidazole derivative followed by carboxylation. Common methods include using N,N'-dicyclohexylcarbodiimide (DCC) as a coupling agent, and the use of triethylamine as a base. The reaction yields high purity product with good selectivity and a yield of up to 85%.
