Adding a certain compound to certain chemical reactions, such as: 6635-90-1, 2-Methoxy-4-methyl-5-nitropyridine, 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, category: pyridine-derivatives, blongs to pyridine-derivatives compound. category: pyridine-derivatives

1. The mixture of 2-methoxy-4-methyl-5-nitropyridine (1.68g, 10.0 mmol) and 1,1- dimethoxy-N,N-dimethylmethanamine (14 Ml, 103 mmol) in 10 mL of DMF was heated at 130C overnight, cooled to RT, diluted with EtOAc, washed with water and brine, dried (MgS04), and concentrated. The residue was dissolved in 70 mL of EtOH. To this solution was added 1.06 g of 10% Pd/C. The mixture was stirred under 1 atm of hydrogen atmosphere over 4 days, filtered through a pad of Celite, and washed with EtOH. The filtrate was concentrated to give crude 5-methoxy-lH-pyrrolo[2,3-c]pyridine (quant). H NMR (399 MHz, DMSO-d6) delta ppm 11.26 (1 H, br. s.), 8.33 (1 H, s), 7.53 (1 H, d, 7=2.7 Hz), 6.73 – 6.88 (1 H, m), 6.32 (1 H, d, 7=3.1 Hz), 3.30 (3 H, s).
