Adding a certain compound to certain chemical reactions, such as: 148870-57-9, name is 7,8-Dimethoxy-3-(3-iodopropyl)-1,3-dihydro-2H-3-benzazepin-2-one, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 148870-57-9, 148870-57-9
7,8-Dimethoxy-3-[3-iodopropyl]-l,3-dihydro-2H-3-benzazepin-2-one (38g) and potassium carbonate (6Og) were added to a mixture of (S)-N-[(4,5-dimethoxybenzocyclobut-l-yl)-methyl]- 7V-(methyl)amine (2Og) and demineralized water (100ml) at room temperature. The reaction mixture was heated and stirred at 50-55 C for 12-16 hours. After completion of reaction, reaction mass was cooled to 25-30 0C and the product is extracted in ethyl acetate (100ml). The aqueous layer was further extracted with ethyl acetate (60ml). Combined ethyl acetate layers was acidified with aqueous hydrochloric acid and stirred. The layers were separated and pH of the aqueous layer was adjusted to 10.5-12.5 with aqueous sodium hydroxide solution. The aqueous layer is extracted with ethyl acetate (140ml + 60ml). Ethyl acetate was distilled out completely under vacuum to get the title compound.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 7,8-Dimethoxy-3-(3-iodopropyl)-1,3-dihydro-2H-3-benzazepin-2-one, other downstream synthetic routes, hurry up and to see.
