Related Products of 89260-46-8<\/a>, 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. 89260-46-8 name is 3-(1H-Pyrazol-3-yl)aniline, 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.<\/p>\n

A cooled (0 0C) solution of 6-(cyclopropylmethyl(propyl)amino)pyrimidine-4- carboxylic acid (Intermediate 21 , 112 mg; 0.45 mmol) in DCM was treated with diisopropylethylamine (78.4 mL; 0.52 mmol) and methyl chloroformate(36.2 mL; 0.47 mmol). After stirring at 0 0C for 15 minutes, 3-(1 H-pyrazol-3- yl)aniline (Apollo, 107 mg; 0.67 mmol) was added and the mixture stirred for 72 hours. The solvent was evaporated and the compound purified by preparative HPLC to give the title compound as a white solid. 1H NMR (400MHz, CDCI3) delta 10.08 (1 H, br s), 8.58 (1 H, s), 8.19 (1 H, s), 7.76 (1 H, d, J = 8.0 Hz), 7.64 (1 H, d, J = 2.3 Hz), 7.57 (1 H, d, J = 7.7 Hz), 7.49- 7.34 (2H, m), 6.67 (1 H, d, J = 2.3 Hz), 3.53 (4H, s), 1.75-1.63 (2H, m), 1.09 (1 H, s), 0.97 (3H, t, J = 7.4 Hz), 0.57 (2H, d, J = 7.7 Hz), 0.35-0.29 (2H, m). MS (ESI-) 375. HPLC (Condition C) Rt 3.75 min (HPLC purity 99.9%).<\/p>\n

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-(1H-Pyrazol-3-yl)aniline, and friends who are interested can also refer to it.<\/p>\n
