With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.19064-65-4,3-Methoxypyridazine,as a common compound, the synthetic route is as follows.
Step 1: A mixture of 3-methoxypyridazine (12.0 mL, 130 mmol) and oxirane-2,2,3,3- tetracarbonitrile (20 g, 140 mmol) in THF (240 mL) was stirred at 0 oC for 2 h and at 4 oC for 40 h. The reaction was concentrated to afford crude dicyano(3-methoxypyridazin-1-ium-1- yl)methanide as a solid, which was taken to the next step without further purification. 1H NMR (DMSO-d6, 400 MHz): delta 8.56 (d, J = 6.0 Hz, 1H), 7.94 (m, 1H), 7.14 (d, J = 9.2 Hz, 1H), 3.97 (s, 3H)., 19064-65-4
19064-65-4 3-Methoxypyridazine 292493, apyridazine compound, is more and more widely used in various fields.
