With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13563-36-5,4-Amino-2-methylpyridazin-3(2H)-one,as a common compound, the synthetic route is as follows.
EXAMPLE 2 5-(2-Bromobenzamido)-1-methyl-6-pyridazone STR7 Analogously to Example 1b) 8.0 g (81.2%) 5-(2-bromobenzamido)-1-methyl-6-pyridazone (active ingredient 1.082) of m.p. 190 to 193 C. was obtained from 4.0 g (0.032 mol) of 5-amino-1-methyl-6-pyridazone in 100 ml of pyridine and 7.7 g (0.035 mol) of 2-bromobenzoyl chloride in 20 ml of dioxane., 13563-36-5
As the paragraph descriping shows that 13563-36-5 is playing an increasingly important role.
