Reference of 35344-95-7, The chemical industry reduces the impact on the environment during synthesis 35344-95-7, name is 1H-Pyrazole-4-carbaldehyde, I believe this compound will play a more active role in future production and life.
1H-pyrazole-4-carbaldehyde (0.5 g; 5.2 mmol) and cesium carbonate (3.39 g; 10.4mmol) were diluted in ACN (10 mL). Then, 2-bromoethyl methyl ether (0.636 mL; 6.77 mmol) was added and the reaction mixture was refluxed for 2 hours. The reaction mixture was partitionned between a saturated solution of NaHCO3 and EtOAc. The organic layer was separated, dried over MgSO4, filtered and concentrated.The residue was purified by silica gel chromatography (irregular Si02, 120 g, DCM/MeOH: 100/0 to 95/5). The fractions containing the product were mixed andconcentrated to afford 439 mg (55percent) of intermediate 35.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1H-Pyrazole-4-carbaldehyde, other downstream synthetic routes, hurry up and to see.
