Application of 3764-01-0 ,Some common heterocyclic compound, 3764-01-0, molecular formula is C4HCl3N2, 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.
In a 500 mL three-necked flask under argon atmosphere, 2,4,6-trichloropyrimidine (5 g, 27.3 mmol), phenylboronic acid (6.7 g, 54.9 mmol), tetrakistriphenylphosphine palladium (1.26 g, 1.09 mmol ), Dimethoxyethane (DME, 100 mL) and a 2M sodium carbonate aqueous solution (82 mL, 164 mmol) were added, and the mixture was reacted for 8 hours while heating and refluxing. After the reaction solution was cooled to room temperature, the aqueous layer was separated and the organic layer was dried over magnesium sulfate. The insoluble material was removed by filtration, and the organic solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography to obtain intermediate (a) (5.6 g, yield 76.9%).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 3764-01-0, 2,4,6-Trichloropyrimidine, other downstream synthetic routes, hurry up and to see.
