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. 658-89-9, name is 4-(Trifluoromethoxy)benzene-1,2-diamine belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 658-89-9
Step a. To a solution of 4-(trifluoromethoxy)benzene-l,2-diamine (CAS Number 658-89-9; 0.45 g, 2.34 mmol) in DMF (5 ml) was added urea (0.28 g, 4.66 mmol) at rt. The resulting reaction mixture was heated at 150C for 20 h. The reaction mixture was diluted with water (5 ml) and the brown precipitate was collected by vacuum filtration and dried under reduced pressure to yield 5- (trifluoromethoxy)-l,3-dihydro-2H-benzo[d]imidazol-2-one (0.28 g, 1.28 mmol). LCMS: Method C, 2.118 min, MS: ES+ 219.
The synthetic route of 658-89-9 has been constantly updated, and we look forward to future research findings.
