Simple exploration of 5-Amino-4,6-dichloropyrimidine

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. 5413-85-4, 5-Amino-4,6-dichloropyrimidine, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 5413-85-4 ,Some common heterocyclic compound, 5413-85-4, molecular formula is C4H3Cl2N3, 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.

A mixture of 4, 6-dichloropyrimidin -5-amine (20.0 g, 122 mmol), ethanamine hydrochloride (EtNH 2 · HCl) (19.9 g, 243 mmol), and potassium carbonate (50.7 g, 367 mmol) in ethanol (100 ml) was heated to 50 for 39 h. The reaction mixture was then cooled to RT, after which it was diluted with DCM (750 ml) and filtered. The filter cake was washed with DCM (250 ml). The combined filtrate was concentrated to dryness to provide 6-chloro -N 4 -ethylpyrimidine-4, 5-diamine MS (ESI) Calc’d for C 6 H 10 ClN 4 [M + H] + 173;. found 173.

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. 5413-85-4, 5-Amino-4,6-dichloropyrimidine, other downstream synthetic routes, hurry up and to see.
