Application of 21597-54-6, The chemical industry reduces the impact on the environment during synthesis 21597-54-6, name is Methyl 3-amino-2-naphthoate, I believe this compound will play a more active role in future production and life.
40 g of compound A-1 (264 mmol) was added to a 500 ml three-necked flask, 16 g of formic acid and 160 ml of formamide were added, and the mixture was heated to 135 C for 5 h, and the reaction of the raw materials was completed by TLC; 200 ml of water was added, and the mixture was kept at 20 to 30 C for 1 h, and filtered. The filter cake was rinsed with water and recrystallized from ethanol to give 36.4 g of Compound A-2, yield 93.1%, purity 98.2%.
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, Methyl 3-amino-2-naphthoate, other downstream synthetic routes, hurry up and to see.
