Application of 3752-24-7, These common heterocyclic compound, 3752-24-7, name is 4,5,6,7-Tetrahydro-1H-benzo[d]imidazole, 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.
EXAMPLE 14 1-[1-(4-Chloro-3-methyl-phenyl)-1H-imidazol-4-yl-methyl]-4,5,6,7-tetrahydro-1H-benzoimidazole-, Hydrochloride (1:2) [1-(4-Chloro-3-methyl-phenyl)-1H-imidazol-4-yl]-methanol was treated first with thionylchloride, then with the reaction mixture of sodium hydride and 4,5,6,7-tetrahydro-benzimidazole. After extractive workup and chromatography the title compound was obtained as the free base. It was converted into its white hydrochloride salt. Mp.>250 C. (MeOH/Et2O), MS: m/e=326 (M+).
Statistics shows that 4,5,6,7-Tetrahydro-1H-benzo[d]imidazole is playing an increasingly important role. we look forward to future research findings about 3752-24-7.
