Electric Literature of 88427-96-7,Some common heterocyclic compound, 88427-96-7, name is 4-(2-Methyl-1H-imidazol-1-yl)benzaldehyde, molecular formula is C11H10N2O, 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.

Working Example 34 4-(6-Chloronaphthanlene-2-sulfonyl)-1-[4-(2-methyl-1H-imidazol-1-yl)benzyl]-2-piperazinone To a solution of N-(tert-butoxycarbonyl)ethylenediamine (431 mg) and 4-(2-methyl-1H-imidazol-1-yl)benzaldehyde (500 mg) in dichloromethane (10 ml) was added acetic acid (323 mg), and the mixture was stirred at room temperature for 1 hour. To the mixture was added, under ice-cooling, sodium triacetoxyborohydride (855 mg), and the mixture was stirred at room temperature for 15 hours. The reaction solution was concentrated, and the residue was dissolved in ethyl acetate. The solution was extracted with water, and the aqueous layer was made alkaline with sodium hydroxide solution. The mixture was extracted with dichloromethane and dried with sodium sulfate, and sodium sulfate was filtered off. To the filtrate was added triethylamine (543 mg) and then was added at 0 C. chloroacetyl chloride (455 mg), and the mixture was stirred at room temperature for 30 minutes. The reaction solution was washed with sodium bicarbonate solution and brine, dried and concentrated, and the residue was dissolved in DMF (15 ml). To the solution was added sodium hydride in oil (129 mg), and the mixture was stirred at room temperature for 3 hours. The reaction solution was concentrated, and the residue was dissolved in ethyl acetate. The solution was washed with water and brine, dried and concentrated, and the residue was purified with column chromatography (ethyl acetate) to give 4-(tert-butoxycarbonyl)-1-[4-(2-methyl-1H-imidazol-1-yl)benzyl]-2-piperazinone.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-(2-Methyl-1H-imidazol-1-yl)benzaldehyde, its application will become more common.
