Application of 30169-25-6, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 30169-25-6 name is 3,6-Bis(3,5-dimethyl-1H-pyrazol-1-yl)-1,2,4,5-tetrazine, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a mixture of 1 (20.5g, 76mmol) in acetonitrile (228ml) was added 80% hydrazine hydrate (4.7g, 76mmol) dropwise at 0C. A red precipitate formed immediately. The mixture was allowed to stir for 30min at ambient temperature, filtered, washed with toluene and dried to give 10.2g of pure material. The mother liquid was concentrated under reduced pressure and the residue treated with toluene, filtered and dried to give an additional 3.3g of pure material for a combined yield of 87.3% of a red solid. mp 135-137C; IR numax (KBr)/cm-1: 3336, 3225, 2929, 1652, 1568, 1481, 1165, 1074; 1H NMR (400MHz, DMSO-d6) delta: 9.75(s, 1H,NH), 6.17(s, 1H, CH), 4.60(s, 2H, NH2), 2.37(s, 3H, CH3), 2.21(s, 3H, CH3); 13CNMR(100MHz, DMSO-d6) delta: 162.9, 157.0, 149.9, 141.2, 108.3, 13.2, 12.0.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3,6-Bis(3,5-dimethyl-1H-pyrazol-1-yl)-1,2,4,5-tetrazine, and friends who are interested can also refer to it.
