Reference of 952511-74-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 952511-74-9, name is 4-Bromo-3-methylbenzene-1,2-diamine belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
3: A mixture of 156 (28 g,140 mmol), formic acid (240 mL) and 37percent> concentrated HC1 (400 mL) was heated to 60 °C for 12 h, cooled in an ice-water bath, and the pH slowly adjusted to 8-9 with 28percent> concentrated NH4OH. The solid was collected by filtration, washed with water and dried in air to afford 25 g (98percent) of 5-bromo-4-methyl-lH-benzo[d]imidazole (158) as a yellow solid: MS (ESI) m/z = 213 [M+l]+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Bromo-3-methylbenzene-1,2-diamine, other downstream synthetic routes, hurry up and to see.
