Synthetic Route of 123-06-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 123-06-8, name is Ethoxymethylenemalononitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A mixture of t-butylhydrazine hydrochloride (4.67 g, 53 mmol) and triethylamine (5.35 g, 53 mmol) in anhydrous ethanol (250 ml) was stirred and ethoxymethylene malononitrile (6.47 g, 53 mmol) was slowly added in portions. The mixture was heated at reflux for 3 hr. The solvent was removed in vacuo and the product was crystallized from ethyl acetate – hexane followed by ether to afford 5-amino-l-tert-butyl-lH-pyrazole-4-carbonitrile as light pale brown crystals (5.6 g, 34.1 mmol); LC/MS, API-ES, Neg, (M-H)”, 163.0.
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, Ethoxymethylenemalononitrile, other downstream synthetic routes, hurry up and to see.
