Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 169770-25-6, name is Methyl 1-methyl-4-nitro-1H-imidazole-2-carboxylate, This compound has unique chemical properties. The synthetic route is as follows., category: imidazoles-derivatives

Methyl-4-nitro-imidazole-2- carboxylate 40 (5 g, 27 mmol) was dissolved in 1 : 1 mixture of MeOH and EtOAc (150 mL). A slurry of moist 10% PdVC in EtOAc was added and the contents were stirred vigorously under hydrogen (70 psi) for 14 h. The reaction mixture was filtered through a bed of celite. The celite was washed with MeOH and the filtrate was concentrated under reduced pressure to furnish crude amine as green solid. The crude amine without any further purification was taken up in CH3CN (150 mL). Contents were cooled to 0 0C and DIEA (6.9 mL, 37.7 mmol) was added. A solution of 1- methyl-4-nitro-2-trichloroacetylpyrrole 23 (7.6 g, 28.2 mmol) in CH3CN (20 mL) was added and the reaction mixture was allowed to stir at ambient temperature for 14 h, EPO during which solid precipitated out. The reaction mixture was filtered to furnish 42 as yellow solid (5 g, 60%). The filtrate was concentrated and the residue was taken up in MeOH. Et2O was added to furnish a second crop of 42 (1 g, 12%). 1H-NMR (DMSO-d6) 611.14 (s, exch, IH, NH), 8.19 (d, IH, J = 1.2 Hz, Py-CH), 7.80 (d, IH, J = 1.2 Hz, Py-CH), 7.68 (s, IH, Im-CH), 3.96 (s, 3H, CH3), 3.94 (s, 3H, CH3), 3.82 (s, 3H, CH3). 13C-NMR (75 MHz, DMSO-d6) 6158.9 (+, s, CO), 157.4 (+, s, CO), 137.1 (+, s, Im-C2), 134.1 (+, s, Py-C4), 131.2 (+, s, Im-C2), 128.2 (-, d, Py-C5), 125.4 (+, s, Py-C2), 1 15.2 (-, d, Im-C5), 1 10.2 (-, d, Py-C3), 52.0 (-, q, OCH3), 37.9 (-, q, CH3), 35.2 (-, q, CH3). EI-HRMS: m/z calcd for Ci3Hi5N5O5 321.1073; found 321.1094 (M+, 20%), 279.0997 (100%), 194.0830 (72%), 153.0317 (35%).
