Downstream synthetic route of 187973-60-0

187973-60-0 6-Iodopyridazin-3-amine 10867834, apyridazine compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.187973-60-0,6-Iodopyridazin-3-amine,as a common compound, the synthetic route is as follows.

187973-60-0, To a solution of compound 3 (1.00 g, 4.52 mmol) in CH2Cl2(15 mL) was added triethylamine (1.57 mL, 11.31 mmol) and themixture was stirred at 0 C to allow addition of di-tert-butyldicarbonate (1.18 g, 5.43 mmol). The resulting solution was stirredat room temperature overnight (16 h). The solvents were evaporated under reduced pressure. A purification by silica columnchromatography using CH2Cl2 as eluent gave the desired derivative17 (1.13 g, 78%) as a beige solid.Mp 171.7 C. 1H NMR (300 MHz, DMSO-d6) d 7.55 (d, 1H,J 9.3 Hz, H4), 6.56 (d, 1H, J 9.3 Hz, H5), 6.55 (bs, 1H, NH), 3.40 (s,9H, 3 CH3).
