Electric Literature of 38696-21-8, 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. 38696-21-8, name is 5-Bromo-N,N-dimethylpyrimidin-2-amine, molecular formula is C6H8BrN3, 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.
A mixture of 5-bromo-N,N-dimethylpyrimidin-2-amine (0.966 g, 4.78 mmol), 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(1,3,2-dioxaborolane) (1.46 g, 5.74 mmol), PdCl2dppf(DCM) (0.114 g, 0.14 mmol) and KOAc (1.407 g, 14.34 mmol) were placed under Ar in a 20 mL microwave flask. Anhydrous 1,2-dimethoxyethane (16 mL) was added and the flask was irradiated at 150 oC for 15 minutes. The reaction was filtered through celite, concentrated and slurried in EtOAc. The reaction was filtered through celite again and the organics were concentrated and purified by column chromatography 0 to 30 % EtOAC in Hexanes. The material was isolated as a light teal solid (0.718 g, 60 % yield). 1H NMR (400 MHz, CDCl3) delta 8.59 (s, 2H), 3.21 (s, 6H), 1.31 (s, 12H).13C NMR (100 MHz, CDCl3) delta 164.1, 83.7, 77.4, 37.2, 25.2, 24.9. HRMS (EI+) m/z calculated for C12H12BN3O2 [M+H]+: 250.1721, found: 250.17189.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 38696-21-8, 5-Bromo-N,N-dimethylpyrimidin-2-amine.
