Reference of 96797-15-8, These common heterocyclic compound, 96797-15-8, name is 4-Iodo-1-trityl-1H-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.
d) Rac-(2-Ethyl-6-methyl-phenyl)-( 1-trityl- lH-imidazol-4-yl)-methanolThis compound was prepared using methodology described in J. Org. Chem. 1991, 56, 5739-5740. To a stirred suspension of 1.47 g (3.37 mmol) 4-iodo-tritylimidazole in 5 ml dichloromethane was added dropwise 1.12 ml (3.37 mmol) of a 3 M solution of ethylmagnesium bromide in diethyl ether at such a rate that the temperature of the reaction mixture did not rise above 28 0C. The resulting solution of ( 1-trityl- IH- imidazo 1-4- yl) -magnesium halide was stirred at room temperature for 30 minutes, and then a solution of 0.50 g (3.37 mmol) 2-ethyl-6-methyl-benzaldehyde in 2 ml dichloromethane was added dropwise over 10 minutes. The reaction mixture was then stirred at room temperature for 5 h, before being quenched by dropwise addition of water and diluted with dichloromethane. The phases were separated and the organic phase was dried over Na2SO4, filtered and concentrated in vacuo to afford 1.40 g (90%) of the title compound as an off-white foam which was used in the next step without further purification.
Statistics shows that 4-Iodo-1-trityl-1H-imidazole is playing an increasingly important role. we look forward to future research findings about 96797-15-8.
