Analyzing the synthesis route of 4,6-Dimethylpyrimidin-2-ol hydrochloride

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,34289-60-6, its application will become more common.

Synthetic Route of 34289-60-6, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 34289-60-6 as follows.

In a 25 ml round bottom flask with stirring bar was combined 2-hydroxy-4,6- dimethylpyrimidine hydrochloride, 2.05 g, cesium carbonate, 5.5g, and dimethyl formamide, 8.5 ml. The mix was stirred 30 minutes, then intermediate 1 c, 1.3g, was added. The resulting mix was heated at 80 0C overnight. TLC with 1 : 1 ethyl acetate/hexanes on silica showed complete conversion to new lower RF spot. The reaction was diluted with water, and extracted with ethyl acetate. The organic layer was washed twice with water. The combined aqueous layers were back extracted with ethyl acetate. The combined organic layers were washed with brine, dried over magnesium sulfate, and then concentrated in vacuo to provide methyl 9-{3-[(4,6-dimethylpyrimidin-2-yl)oxy]propyl}- 2,3,4,9-tetrahydro-lH-carbazole-6-carboxylate as an orange oil.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,34289-60-6, its application will become more common.
