104618-32-8,Some common heterocyclic compound, 104618-32-8, name is 2-(4-Oxocyclohexyl)isoindoline-1,3-dione, molecular formula is C14H13NO3, 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 3 3-Amino-6-methoxy-1,2,3,4-tetrahydrocarbazole hydrochloride Reaction of 4-methoxyphenyl hydrazine hydrochloride (0.87g, 5.0 mmol) with 4-phthalimido-cyclohexanone (1.22g, 5.0 mmol) in ethanol (20 ml) heated under reflux for 2 hr, followed by cooling and removal of the precipitated solid by filtration gave 3-phthalimido-6-methoxy-1,2,3,4-tetrahydrocarbazole (1.62g).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 104618-32-8, its application will become more common.
