Procedure
222 mL (1.59 mol) of triethylamine are added to a solution of 300 mL (1.59 mol) of 2,6-diisopropyl-phenylamine (Starting material 3) in 1 liter of dichloromethane. The reaction mixture is cooled to 0° C., and 127 mL (1.59 mol) of chloroacetyl chloride are then added dropwise. Once the addition is complete, the ice bath is removed and the medium is stirred for 20 minutes. It is then poured into water and extracted with dichloromethane. The organic phases are combined and washed with water. They are dried over sodium sulfate. The solvents are evaporated off. The residue is filtered through a pad of silica (eluent: dichloromethane). The filtrate is evaporated and then triturated in heptane. 2-Chloro-N-(2,6-diisopropyl-phenyl)acetamide is obtained in the form of a white solid.
