18672-03-2, name is 5,6-Dichloro-1H-benzo[d]imidazol-2-amine, belongs to imidazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Application In Synthesis of 5,6-Dichloro-1H-benzo[d]imidazol-2-amine
EXAMPLE 25 7,8-Dichloro-1,2-dihydro-2,2,3-trimethyl-1,3,5-triazino[1,2-a]benzimidazol-4(3H)-one Reaction of 2-amino-5,6-dichlorobenzimidazole with acetone and methyl isocyanate according to the procedure of Example 1, first paragraph, provided the title compound. In this case, a 10-N-methylcarbamoyl derivative was not isolated from the reaction mixture. The product was recrystallized from acetone to give a solid, mp 220 C. (dec.). The confirmatory elemental analysis is shown in Table III.
The synthetic route of 18672-03-2 has been constantly updated, and we look forward to future research findings.
