Adding a certain compound to certain chemical reactions, such as: 2851-13-0, name is N,N-Dimethyl-1H-benzo[d]imidazol-2-amine, belongs to imidazoles-derivatives compound, 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 2851-13-0, category: imidazoles-derivatives
2-Acetylpyridine (1.12 cm3, 9.9 mmol) was added consecutively by syringe, to a solution of 2-(1-methylhydrazinyl)-1Hbenzo[d]imidazole (1.62 g, 9.9 mmol) in ethanol. The mixture was stirred and heated at 60 C for 48 h. The product was isolated by evaporation of the solvent and recrystallization of the residue from a minimum volume of CH3CN by the gradual addition of diethyl ether. Yield: 83% (2.19 g). ESI-MS: m/z (%) = 266 (100) [L+H]+, 288(30) [L+Na]+. 1H NMR (300 MHz, CD3CN): 8.21 (d, J = 4.5 Hz, 1H),7.73 (d, J = 8.0 Hz, 1H), 7.57 (t, J = 7.8 Hz, 1H), 7.06-7.23 (m, 5H),3.48 (s, 3H, CH3-N), 3.48 (s, 3H, CH3-CN) ppm. 13C NMR (CD3CN,100 MHz): 162.04, 157.09, 155.16, 148.93, 148.72, 136.81, 136.29,127.07, 124.41, 121.62, 77.31, 76.99, 76.54, 40.26, 16.38 ppm. IR (KBr): m(C-H)ar 3075m, 3058s, 3029s, m(CC) 1580m, 1564m,1517w, 1456s; m(CN) 1442s, 1400m, 1346w, 1311s, q(C-H)1198s, 1170vs, 1143m, 1085s, 990s, 952s, 885vs; c(C-H) 837s,806m, 789s, 762m, 735m, 641s, 608s, 548m, 438s, 414s cm1. Anal.Calc. for C15H15N5 (265.32): C, 67.90; H, 5.70; N, 26.4. Found: C,67.82; H, 5.77; N, 26.32%.
