Application of 51-06-9, 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. 51-06-9 name is 4-Amino-N-(2-diethylaminoethyl)benzamide, 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.
A mixture of p-SCN-Bn-NOTA (0.05 g, 0.09 mmol) and 4-amino-N-(2-(diethylamino)ethyl)benzamide (0.030 g, 0.11 mmol) in CHCl3 (1 mL) containing TEA (45 muL, 0.27 mmol) was stirred 24 h at room temperature. The solvent was evaporated under reduced pressure. The resulting product was purified by semi-preparative HPLC (gradient 10% of H2O for 5 min and 10-70% of MeCN for 30 min; flow rate, 2 mL/min; 240 nm; tR, 12 min) to give SCN-NOTA-BZA as a pale yellow solid (46 mg, 75%). MS (FAB) m/z 686, (M+H)+; HRMS of C33H48N7O7S 686.3336 (calculated) and 686.3340 (observed); 1H NMR (500 MHz, D2O): delta 7.68 (d, 1H), 7.34 (d, 2H), 7.20 (m, 4H), 3.67-3.65 (br, 2H), 3.54-3.50 (br, 2H), 3.39-3.29 (br, 4H), 3.20-3.12 (br, 6H), 3.09-2.99 (br, 8H), 2.92-2.52 (br, 3H), 1.20-1.14 (br, 8H); 13C NMR (125 MHz, D2O): delta 179.3, 178.5, 176.3, 174.4, 169.8, 142.0, 136.8, 136.1, 130.3, 130.0, 129.8, 128.8, 128.2, 126.0, 125.6, 124.5. 60.6, 57.8, 57.6, 57.2, 57.1, 52.4, 52.1, 51.6, 50.6, 47.6, 46.6, 46.0, 43.5, 34.9, 33.7, 33.6, 8.2, 8.1.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-Amino-N-(2-diethylaminoethyl)benzamide, and friends who are interested can also refer to it.
