White to yellow to light brown solid | [Uses]
5-Bromo-2-(methylthio)pyrimidine-4-carboxylic acid serves as a precursor for synthesizing pyrimidine-4-carbohydrazide via reaction with hydrazine hydrate in ethanol under reflux, and for producing intermediates bearing a methyl sulfide group[5-6].
| [Synthesis]
Mucobromic acid (58.05 g, 0.225 mol) was slowly added to a stirring aqueous solution (500 mL) of S-methylisothiourea sulfate (62.66 g, 0.225 mol) at room temperature. Subsequently, the reaction suspension was cooled to 10 °C (using an ice bath) and triethylamine (94.1 mL, 0.675 mol) was added dropwise over 4 hours. After the dropwise addition was completed, the reaction mixture was allowed to stand at room temperature for 24 hours. Upon completion of the reaction, activated carbon (Darco G-60) was added to the dark red/brown solution and the activated carbon was removed by filtration after stirring for 10 minutes. The filtrate was acidified with concentrated hydrochloric acid (50 mL) and the precipitated yellow precipitate was collected by filtration and washed sequentially with water (2 x 80 mL) and ether (2 x 100 mL). Finally, the product was dried in a vacuum oven at 50 °C for 2 days to afford 2-(methylthio)-5-bromo-4-pyrimidinecarboxylic acid (33.13 g, 59% yield) as a yellow amorphous solid.1H NMR (DMSO-d6, 400 MHz) δ: 2.75 (s, 3H), 9.20 (s, 1H). | [References]
