实验步骤: To a stirred solution of 15.0 grams (0.05 mole) of 2,4-dichloro-3,5-dinitrobenzotrifluoride and 4.97 grams (0.05 mole) of triethylamine in 200 ml. of dimethoxyethane was added, dropwise, 4.28 grams (0.05 mole) of N-cyclopropylmethyl-N-ethylamine at room temperature over a period of 2.5 hours. The resultant mixture was then heated under reflux for 16 hours. The solvent was removed by evaporation under reduced pressure and the residue then dissolved in a mixture of chloroform and water. The organic layer was separated and was washed with water, dilute hydrochloric acid, dilute sodium bicarbonate, and then water. After drying over anhydrous sodium sulfate, the organic solution was evaporated to dryness. The residue was dissolved in hexane and filtered and then evaporated to dryness to give 12.85 grams of the product as as dark, viscous amber liquid. under reflux for 16 hours The solvent was removed by evaporation under reduced pressure the residue then dissolved in a mixture of chloroform and water The organic layer was separated was washed with water, dilute hydrochloric acid, dilute sodium bicarbonate After drying over anhydrous sodium sulfate the organic solution was evaporated to dryness The residue was dissolved in hexane filtered evaporated to dryness
