Some tips on 4359-87-9

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. 4359-87-9, 2,4,6-Trichloro-5-nitropyrimidine, other downstream synthetic routes, hurry up and to see.

Application of 4359-87-9 ,Some common heterocyclic compound, 4359-87-9, molecular formula is C4Cl3N3O2, 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.

Dissolve 2,4,6-trichloro-5-nitropyrimidine (454 mg, 2.0 mmol) and diisopropylethylamine (516 mg, 4.0 mmol) in anhydrous tetrahydrofuran (20 mL), and slowly add dropwise at 0 C. 2,4-difluorobenzylamine (300 mg, 2.1 mmol) was stirred at 0 C for 1 hour. Concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (petroleum ether: ethyl acetate = 15: 1) to obtain 34-e (547 mg, yield: 82%) as a yellow solid.

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. 4359-87-9, 2,4,6-Trichloro-5-nitropyrimidine, other downstream synthetic routes, hurry up and to see.
