As a common heterocyclic compound, it belongs to cinnoline compound, name is Cinnoline-4-carboxylic acid, and cas is 21905-86-2, its synthesis route is as follows.
EXAMPLE 2 Potassium Cinnoline-4-carboxylate (2) 5.10 g of (1) was added over 30 minutes to a vigorously stirred solution of 2.02 g of potassium carbonate in 25 ml of water, at room temperature. The resulting mixture was stirred for one hour at room temperature, then treated with charcoal, and after filtration the water was evaporated. The residue was azeotropically distilled with toluene and dried at 70 C. under reduced pressure, to give 2, as a light tan powder, m.p.: above 280 C.
21905-86-2, 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.,21905-86-2 ,Cinnoline-4-carboxylic acid, other downstream synthetic routes, hurry up and to see
