Pyrrolo[2,1-f][1,2,4]triazine-6-carboxylic acid, 1,4-dihydro-5-methyl-4-oxo-, ethyl ester Usage And Synthesis

Synthesis

1. The compound (CAS: 77287-34-4) was mixed with diethyl 1-amino-3-methyl-1H-pyrrole-2,4-dicarboxylate in formamide (8 mL) and 20 wt% acetic acid (2 g) was added. 2. The reaction mixture was heated at 120°C for 24 hours. 3. Upon completion of the reaction, it was cooled to room temperature and water (32 mL) was slowly added to precipitate the target product, ethyl 5-methyl-4-oxo-3,4-dihydropyrrolo[1,2-F][1,2,4]triazine-6-carboxylate. 4. The precipitated solid was collected by filtration and washed with ethyl acetate (EtOAc). 5. Drying gave the target compound as a yellow solid in 90% yield.
