According to the analysis of related databases, 7752-82-1, the application of this compound in the production field has become more and more popular.

Electric Literature of 7752-82-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 7752-82-1, name is 5-Bromopyrimidin-2-amine, molecular formula is C4H4BrN3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

Step A: A mixture of 2-amino-5-bromopyrimidine (2.75 g, 15.8 mmol) and di-tert- butyl dicarbonate (7.58 g, 34.8 mmol) in pyridine (30 mL) was stirred at 70 C overnight, then the solvent was removed. The residue was partitioned between EtOAc and aqueous HC1 (1 N). The aqueous layer was extracted with EtOAc. The combined organics were dried over NaS04, then filtered and concentrated to give 2-[bis(tert-butoxycarbonyl)amino]-5-bromopyrimidine (5.5 g, 93%) as a white solid. MS m/z 398.2 [M+Na]+.

According to the analysis of related databases, 7752-82-1, the application of this compound in the production field has become more and more popular.
