The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 4316-97-6, name is 4,6-Dichloro-5-methylpyrimidine. This compound has unique chemical properties. The synthetic route is as follows. Application In Synthesis of 4,6-Dichloro-5-methylpyrimidine
To a solution of 2-[2-fluoro-4-[[4-(trifluoromethyl)-2-pyridyl]oxy]phenyl]ethanamine hydrochloride (378 mg, 1 mmol) in N-methyl-2-pyrrolidone (5 mL) was added diisopropylethylamine (0.4 mL, 2.3 mmol). The solution was stirred for 5 min at room temperature at which time 4,6-dichloro-5- methylpyrimidine (150 mg, 0.8 mmol) was added. The reaction mixture was stirred at 80C overnight then allowed to cool to room temperature. Water was added and was extracted with MTBE (3x). The combined organic layers were washed with water, dried over Na2S04, and concentrated in vacuo. The residue was purified by flash silica column chromatography to provide 330 mg (0.80 mmol, 84%) of the light yellow solid product.
With the rapid development of chemical substances, we look forward to future research findings about 4316-97-6.
