27258-33-9, Name is 1-Methyl-1H-pyrazole-5-carbaldehyde, 27258-33-9, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows.
A mixture of 1-methyl-1H-pyrazole-5-carbaldehyde (5.0 g, 45.4 mmol), N-iodosuccinimide(15.3 g, 68.1 mmol), and TFA (50 mL) was stirred at room temperature for 1.5 h. H20 (50mL) was added, and the precipitate was filtered, rinsed with H20 (100 mL), and dried toafford the title compound (9.03 g, 84%).?H NMR (500 MHz, CDC13) oe ppm 4.19 (s, 3H), 7.58 (s, 1H), 9.80 (s, 1H)
