Related Products of 106131-61-7,Some common heterocyclic compound, 106131-61-7, name is 3,6-Dichloro-1,2,4,5-tetrazine, molecular formula is C2Cl2N4, 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.
To a solution of 3,6-dichloro-1,2,4,5-tetrazine (500 mg, 3.31 mmol) in Tol. (5 mL) was added 2-methylbut-3-yn-2-ol at 20 C. The mixture was stirred at 115 C. for 16 hours under sealed tube. LCMS showed desired MS. The reaction mixture was concentrated under reduced pressure to give a residue. The residue was purified by column chromatography (SiO2, petroleum ether:ethyl acetate=10:1 to 4:1, TLC) to give 33a. MS mass calculated for [M+1]+ (C7HCl2N2O) required m/z 207.0, LCMS found m/z 207.0; 1H NMR (400 MHz, CDCl3) delta 7.98 (s, 1H) 2.17 (s, 1H) 1.77 (s, 6H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,6-Dichloro-1,2,4,5-tetrazine, its application will become more common.
