Synthetic Route of 114041-16-6,Some common heterocyclic compound, 114041-16-6, name is 5,6-Dimethoxyisoindoline, molecular formula is C10H13NO2, 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.
Step e: simultaneous preparation of 1-(5,6-dimethoxyisoindolin-2-yl)-6-[4-(3-trifluoromethyl-phenyl)piperazin-1-yl]hexan-1-one, 1-isoindolin-2-yl-6-[4-(2-cyanophenyl)piperazin-1-yl]hexan-1-one and 1-isoindolin-2-yl-6-[4-(2-methyl-phenyl)piperazin-1-yl]hexan-1-one A mixture of 0.3 mmol of dicyclohexylcarbodiimide and 0.3 mmol of 1-hydroxybenzotriazole is added to a solution of acid (0.3 mmol) in 2 mL of anhydrous N,N-dimethylformamide. The mixture is left whilst stirring for four hours at 70 C. It is then cooled at ambient temperature, filtered in order to eliminate the dicyclohexylurea. Amine (0.2 mmol) is then added, then it is left for twenty hours at ambient temperature. The N,N-dimethylformamide is evaporated out in a vacuum and the crude is taken up by 2 mL of dichloromethane. It is then washed twice with 1 mL of a normal aqueous solution of soda, then with 1 mL of water. The organic phase is dried then concentrated in a vacuum. Starting from 6-[4-(3-trifluoromethyl-phenyl)piperazin-1-yl]hexanoic acid and 5,6-dimethoxyisoindoline, 1-(5,6-dimethoxyisoindolin-2-yl)-6-[4-(3-trifluoromethylphenyl)piperazin-1-yl]hexan-1-one is obtained in this way. Rf: 0.76 dichloromethane/methanol 85/15
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5,6-Dimethoxyisoindoline, its application will become more common.
