4-BROMO-3,5-DIMETHYL-BENZONITRILE Use and Manufacturing
To a 100 ml three-necked flask at room temperature, the compound of Formula III (0.9 g, 3.24 mmol) was added.ammonium hydroxide (4.41 g, 64.8 mmol) is turned on with stirring, iodine (0.8 g, 6.28 mmol), Acetonitrile (9 mL) was heated to 60° C. under nitrogen protection and maintained at the temperature for 4 hours.TLC controls the reaction of raw materials and stops heating.Cool down to room temperature (20-30°C), evaporate the solvent under reduced pressure at 40°C, and add 20 mL of ethyl acetate.The liquid was separated, and the organic phase was washed with 10 mL of water and washed with 10 mL of saturated aqueous sodium chloride solution.Drying over anhydrous sodium sulfate and concentration of the solvent yielded 0.7 g of the crude compound of formula IV as a pale yellow waxy solid, Recrystallization from 1 mL of isopropanol gave an off-white solid.Yield: 0.5 g, yield: 73.5percent.
