Reference of 31037-02-2, 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. 31037-02-2 name is Ethyl 5-amino-1-methyl-1H-pyrazole-4-carboxylate, 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.
The ligand, L (0.169 g; 1 mmol), was dissolved in hot MeOH (5 cm3), and CuBr2 (0.11 g; 0.5 mmol) was added. Two days later, the brown needle-like microcrystals were filtered and washed with MeOH and Et2O. Yield: 0.143 g (54%). Calcd.(Found) for CuC14H22N6Br2: C, 29.93; H, 3.92; N, 14.96. (C,29.79; H, 3.93; N, 14.94). IR bands [ v/cm-1]: 3488, 3441,3348, 1683, 1632, 1557, 1458, 1124, 773. Molar conductivity, LambdaM (S cm2 mol-1): 61 (DMF).
