Reference of 61655-72-9, A common heterocyclic compound, 61655-72-9, name is 6-Chloro-N,N-dimethylpyrazin-2-amine, molecular formula is C6H8ClN3, 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.

EXAMPLE 24 6-(N,N-dimethylamino)-2-(1-piperazinyl)pyrazine dihydrochloride Twenty millimoles (3.14 g.) of 6-(N,N-dimethylamino)-2-chloropyrazine and piperazine (3 g.) are fused under N2 at 135° for 6 hours. The mixture is digested with water and after filtering to remove insolubles, is basified with 10 N sodium hydroxide and extracted with chloroform. The combined chloroform extracts are washed with 2 N sodium hydroxide, dried (sodium sulfate, anhyd.), filtered, and concentrated to an oil under reduced pressure. The product is isolated as the dihydrochloride salt, m.p. 249°-250°, from isopropanol.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

A mixture of 6- cMoro-N,N-dimethylpyrazin-2-amine (11-2) ( 1 g, 6.3 mmol) and pyridin-4-yl boronic acid (1.06 g, 8.6 mmol, 1.35 eq) were suspended in dimethoxyethane and water (10:1 ) in a heavy wall pressure vessel. The reaction mixture was purged with argon for 10 min. Sodium carbonate (2.0 g, 1 ,6 mmol, 3 eq) and tetrakis(triphenylphosphine) palladium (0.650 g, 0.57 mmol) were added and the reaction mixture was heated at 1 10 ¡ãC for 15 hrs. The reaction mixture was cooled to ambient temperature and filtered though a medium frit sintered glass funnel filled with Celite. The filtrate was concentrated under reduced pressure, dissolved in dichloromethane and washed with water (3 x 5 mL). The organic layer was dried with sodium sulfate and concentrated under reduced pressure. The product 11-3 was purified over silica gel column using ethylacetate and hexane (2:3 v/v) eluent. The title compound 11-3 was obtained as yellow solid (1 , 1 g) in 75percent (gravimetric) yield. HPLC (tr/purity): 10.7 min, > 90percent (HPLC method A); ESI m/z (MeOH) : 201.10 (MH ).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6-Chloro-N,N-dimethylpyrazin-2-amine, its application will become more common.
