Application of 3097-21-0, These common heterocyclic compound, 3097-21-0, name is 1,3-Dimethyl-1H-benzo[d]imidazol-2(3H)-one, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Take 1,3-dimethyl-1,3-dihydro-2H-benzo [d] imidazol-2-one (1.0 g, 6.1 mmol),Add to chlorosulfonic acid and react at room temperature for 5 hours;After the reaction is completed, water is added to precipitate a solid, which is filtered with suction, recrystallized, and filtered with suction, and the filter cake is dried under infrared.A gray solid was obtained with a yield of 88%.
The synthetic route of 3097-21-0 has been constantly updated, and we look forward to future research findings.
