Adding a certain compound to certain chemical reactions, such as: 41663-84-7, name is 2-Methyl-5-nitroisoindoline-1,3-dione, 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 41663-84-7, HPLC of Formula: C9H6N2O4
EXAMPLE I In a 500 ml three-necked flask equipped with a mechanical stirrer, Dean-Stark trap/condenser, nitrogen inlet, and thermometer was added 25.71 grams (0.20 moles) of p-chlorophenol, 100 ml dimethylsulfoxide, and 150 ml of chlorobenzene. After stirring and nitrogen purging the mixture for 30 min., 15.80 grams of aqueous sodium hydroxide (50.62 wt. %; 0.20 moles) was added. The mixture was heated up to 150 C. with the azeotropic removal of the water of reaction. After the removal of water was complete the temperature was lowered to 60 C. and 41.23 grams (0.20 moles) of 4-nitro-N-methyl phthalimide was added. The mixture was stirred overnight. Upon cooling to room temperature the product precipitated from solution. Filtration, washing the precipitate with water, and recrystallization from isopropanol yielded 50.8 grams of 4-(p-chlorophenyl)-N-methyl phthalimide. The melting point was 131-132 C.
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, 2-Methyl-5-nitroisoindoline-1,3-dione, other downstream synthetic routes, hurry up and to see.
