Adding a certain compound to certain chemical reactions, such as: 709652-82-4, 2-Amino-5-bromonicotinonitrile, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, name: 2-Amino-5-bromonicotinonitrile, blongs to pyridine-derivatives compound. name: 2-Amino-5-bromonicotinonitrile
A suspension of 2-amino-5-bromo-3-pyridinecarbonitrile (0.59 g, 3 mmol), DMF-DMA (1 ml, 7.5 mmol), and MeCN (2 ml) was irradiated at 50 C (input power of: 200 W) for2 min. The resulting mixture was cooled to room temperature and poured onto ice cold water. The precipitate was filtered off, washed with water, and dried to afford (1E)-N?-(3-cyano-2-pyridinyl)-N,N-dimethylmethanimidamide (Lacbay et al. 2014). Light yellow solid; yield 95%; m.p. 116-117 C; 1H NMR (400 MHz, DMSO-d6) delta 8.65-8.60 (m, 1H, H-5), 8.46 (d, J = 2.6 Hz, 1H, H-3), 8.32 (d,J = 2.6 Hz, 1H, N=CH), 3.16 (s, 3H, CH3),3.07 (s, 3H,CH3); 13C NMR (100 MHz, DMSO-d6) delta 162.27 (C-2),157.00 (C=N), 153.23 (C-6), 144.32 (C-4), 116.77 (CN), 110.23 (C-5), 102.68 (C-3), 35.00 (C-N); IR (film): 3457(C-N), 3061, 2916, 2795, 2483, 2306, 2214 (CN), 1960, 1625 (C=N), 1562, 1395 cm-1; HRMS (ESI) m/z: calculatedfor C9H10BrN4+ [M + H]+: 253.0089; found: 253.0084.
The synthetic route of 709652-82-4 has been constantly updated, and we look forward to future research findings.
