With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1235450-86-8, name is 5-Bromo-2-ethylpyrimidine-4-carboxylic acid, molecular formula is C7H7BrN2O2, molecular weight is 231.05, as common compound, the synthetic route is as follows.Quality Control of 5-Bromo-2-ethylpyrimidine-4-carboxylic acid
A mixture of 5-Bromo-2-ethylpyrimidine-4-carboxylic acid (5.6 g, 24.3 mmol) in xylene (50 mL) was refluxed for 2 h. After cooling, the mixture was applied directly to a silica column, which was eluted with petroleum ether, then ethyl acetate in petroleum ether (5%) to give compound 0601-121 (1.7 g, 38%) as a yellow liquid. 1H NMR (400 MHz, DMSO-d6): 1.26 (t, J=7.6 Hz, 3H), 2.87 (q, J=7.6 Hz, 2H), 8.90 (s, 2H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1235450-86-8, 5-Bromo-2-ethylpyrimidine-4-carboxylic acid, and friends who are interested can also refer to it.
