Step 1 Synthesis of methyl 1H-imidazole-4-carboxylate: 1H-imidazole-4-carboxylic acid (1.0 g, 8.9 mmol) was mixed with concentrated sulfuric acid (1 mL) in methanol (30 mL), stirred and heated to 0 °C. The reaction mixture was reacted under reflux conditions overnight. Upon completion of the reaction, the mixture was concentrated under reduced pressure and subsequently partitioned between cold water and ethyl acetate. The organic layer was separated and concentrated under reduced pressure to afford methyl 1H-imidazole-4-carboxylate (1 g, 89% yield).
