Synthetic Route of 6780-38-7,Some common heterocyclic compound, 6780-38-7, name is 2-(1,3-Dioxoisoindolin-2-yl)acetyl chloride, molecular formula is C10H6ClNO3, 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.
271 g of water was put in a 1 L four-necked flask and cooled to 10 C. 7 7 g (570.4 mmol) of potassium carbonate was added thereto and dissolved. This was cooled to 3 C. and 30.1 g (223.2 mmol) of 2,2,2-trifluoroethylamine hydrochloride was added thereto. The solution was stirred at 3 C. for 10 minutes, and a solution of 50 g (223.2 mmol) of phthaloylglycyl chloride dissolved in 150.7 g of acetonitrile was added dropwise thereto at such a rate that the reaction solution kept at 20 C. or lower. After stirring for 1 hour, the product precipitated in the reaction was filtered and washed with 150.7 g of water. The obtained solid was dried under reduced pressure at 60 C. to obtain 2-phthaloyl-N- (2,2,2-trifluoroethyl) acetamide as a white solid. The yield was 59.7 g, and the yield was 93.5%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(1,3-Dioxoisoindolin-2-yl)acetyl chloride, its application will become more common.
