反应详情

To a stirred mixture of 5.7 parts of lithium aluminum hydride in 20 parts of ether is added dropwise a solution of 15 parts of 2-cyano-3-chlorotoluene in 140 parts of ether at reflux temperature. After the addition is complete, stirring at reflux temperature is continued for one hour. The reaction mixture is cooled in an ice-bath and decomposed with 25 parts of water and with a 20% solution of potassium-sodium tartrate (450 parts). The aqueous phase is separated and extracted with ether. The combined ether layers are washed with water, dried, filtered and evaporated. The oily residue is distilled in vacuo, yielding 12 parts of 2-chloro-6-methylbenzylamine; bp. 113° -118° C at 18 mm. pressure.
