Synthetic Route of 50593-92-5 , The common heterocyclic compound, 50593-92-5, name is 5-Bromo-2-(methylthio)pyrimidine-4-carboxylic acid, molecular formula is C6H5BrN2O2S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Preparation 29 (1052) Methyl 5-bromo-2-(methylthio)pyrimidine-4-carboxylate (1053) A solution of 5-bromo-2-(methylthio)pyrimidine-4-carboxylic acid (7.64 g, 30.7 mmol) in MeOH (60 ml_) was treated with sulfuric acid (2 ml_) and heated to reflux for 24 hours. The mixture was poured onto ice water and extracted with DCM. The organic layer was washed with saturated aqueous NaHC03, dried (MgS04) and concentrated in vacuo to afford the title compound (6.42 g, (1054) 80%). (1055) 1 H NMR (500 MHz, CDCb): delta ppm 8.72 (s, 1 H), 4.01 (s, 3H), 2.58 (s, 3H). LCMS (ESI) Rt = 2.35 minutes, MS m/z 263 [M+H]+
The synthetic route of 50593-92-5 has been constantly updated, and we look forward to future research findings.
