711007-44-2, A common compound: 711007-44-2, name is 2,3-Diaminobenzamide, belongs to amides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
General procedure: In a dark environment, a mixture of 2,3-diaminobenzamide(1.51 g, 10 mmol), PYTZ (20 mg), and ethanol (200 mL)was taken in an open pear-shaped bottle, stirred magneticallyat room temperature, and then aldehyde (10 mmol) wasadded slowly in 2 min. The bottle was exposed to visiblelight (Xenon, 10 A) under stirring condition. The reactionwas monitored by TLC. After the reaction completed, thereaction mixture was transferred to a three-neck bottle outsideof the photochemical reactor and air was introduced toensure that the intermediate was completely oxidized. Then,the solvent was evaporated in vacuum to 40 mL until thesolid appeared. The mixture was cooled down in an ice bathfor crystallization, filtration. The crude solid was recrystallizedfrom 25 mL ethanol (30 C) to get the target products.
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, 2,3-Diaminobenzamide, other downstream synthetic routes, hurry up and to see.
