Synthetic Route of 628-20-6, 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. 628-20-6, name is 4-Chlorobutyronitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 41 5-(3-Chloropropyl)Tetrazole A mixture of 3.5 g of 4-chlorobutyronitrile, 2.3 g of sodium azide and 1.9 g of ammonium chloride in 50 ml of dimethylformamide is stirred at 140 C. for 20 hours. The reaction mixture is poured onto ice, basified with 1N sodium hydroxide and extracted twice with ethyl acetate. The aqueous fraction is acidified with acetic acid and extracted with ethylacetate. Evaporation of the ethyl acetate gives 5-(3-chloropropyl)tetrazole which is used directly in the next step.
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, 4-Chlorobutyronitrile, other downstream synthetic routes, hurry up and to see.
