These common heterocyclic compound, 17289-26-8, name is 1-Methyl-1H-imidazole-4-carbaldehyde, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. HPLC of Formula: C5H6N2O
2-Amino-5-methyl-4-phenylthiophene-3-carboxamide 123 (1.0 eq) was refluxed with 1-methylimidazole-4-carboxaldehyde (1.1 eq) in acetic (5 mL) acid for 24h. After completion of the reaction (confirmed by TLC), solution was cooled and diluted with water. The precipitate was filtered off and dried to give compound 126 (Yield -87%) as a brown solid. The scale was calculated on 700 mg theoretical yield of product. Yield: 609 mg (87 %).
The synthetic route of 1-Methyl-1H-imidazole-4-carbaldehyde has been constantly updated, and we look forward to future research findings.
