In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 124750-59-0, name is 2-Propyl-1H-imidazole-4,5-dicarboxylic acid dimethyl ester belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 124750-59-0
PART A: Preparation of 4,5-Bis(methoxycarbonyl)-1-(4-bromophenyl)methyl-2-propylimidazole A solution of 40.0 g (0.177 mole) of 2-propyl-4,5-bis(methoxycarbonyl)-imidazole and 44.6 g (0.178 mole) of 4-bromobenzyl bromide in 350 mL of DMF was stirred in the presence of 37.5 g (0.271 mole) of K2 CO3 overnight at room temperature. The reaction mixture was then poured into 1200 mL of water and extracted with 3*300 mL of ether. The combined ether extracts were washed with 8*1000 mL of water and once with brine, then dried over MgSO4. The solvent was removed under reduced pressure to yield 61.8 g (88%) of the title compound as a solid. 1 H NMR (300 MHz, CDCl3): delta0.94 (t, J=7.6 Hz, 3H); 1.73 (m, 2H); 2.63 (t, J=7.9 Hz, 2H); 3.81 (s, 3H); 3.93 (s, 3H); 5.37 (s, 2H); 6.86 (d, J=8.8 Hz, 2H); 7.45 (d, J=8.8 Hz, 2H). MS [DCI (NH3)]: m/z 395/397 (M+H, 1 Br).
The synthetic route of 124750-59-0 has been constantly updated, and we look forward to future research findings.
