Adding a certain compound to certain chemical reactions, such as: 675109-26-9, name is 6-Bromoisoindolin-1-one, belongs to indolines-derivatives 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 675109-26-9, SDS of cas: 675109-26-9
Preparation 48: 6-bromo-2-[2-(morpholin-4-yl)ethyl]-2,3-dihydro-1 H-isoindol-1 -one (1544) (1545) Sodium hydride (60% dispersion in mineral oil, 34 mg, 1.40 mmol) was added to a suspension of 6-bromo-2,3-dihydro-1 H-isoindol-1 -one (250 mg, 1.18 mmol) in DMF (5 mL) and the mixture was stirred for 5 min after hydrogen gas evolution ceased. 4-(2-bromoethyl)morpholine (0.18 mL, 1.3 mmol) was added to the resulting brown solution and the mixture was stirred at RT for 18 h. The mixture was diluted with ethyl acetate and transferred into a separating funnel. Water was added and the crude product was extracted with ethyl acetate. The combined organic extracts were washed with brine, dried (MgS04) and concentrated under vacuum. The residue was triturated with a mixture of diethyl ether and iso-hexane and the resulting precipitate was filtered, washed with iso-hexane and dried under suction to afford the title compond (196 mg, 50%) as a pale yellow solid. LC-MS: [M+H]+ = 325/327.
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, 6-Bromoisoindolin-1-one, other downstream synthetic routes, hurry up and to see.
