Electric Literature of 84487-15-0, Adding some certain compound to certain chemical reactions, such as: 84487-15-0, name is 2-Bromo-5-nitropyridin-4-amine,molecular formula is C5H4BrN3O2, 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 84487-15-0.
A solution of 2-bromo-5-nitropyridin-4-amine (1.5 g, 6.9 mmol) in acetic acid (20 mL) was added in portions into a 75 C suspension of iron powder (1.5 g, 27 mmol) in acetic acid (20 mL). The reaction mixture was stirred at 75 C for 2 h, cooled to room temperature, and filtered through celite. To the filtrate was added 1,3-bis(methoxycarbonyl)-2-methyl-2- thiopseudourea (1.4 g, 6.9 mmol), and the mixture was stirred at 65 C for 60 h. The reaction mixture was cooled to room temperature and concentrated. The solid residue was triturated with dichloromethane and dried to give the title Compound (1.8 g, quantitative yield) as an orange solid. MS (EI) for C8H7BrN4O2: 271/273 (MH+).
