实验步骤: A mixture containing 300 ml of toluene and 31 ml of 2-isopropylaniline is cooled in ice, and 22 ml of acetic anhydride are added slowly. After 40 minutes with stirring at RT, the reaction medium is evaporated and the residue is then taken up with petroleum ether. The precipitate formed is drained. 35.9 g of the expected product are obtained after crystallization in petroleum ether, m.p.=81° C. is cooled in ice the reaction medium is evaporated The precipitate formed

实验步骤: 86 g of acetic acid anhydride were added to a solution of 108 g of 2-isopropyl-aniline and 250 ml of benzene and another 86 g of acetic acid anhydride were added thereto. The mixture was stirred at 20° C. for 16 hours and was washed with water, with aqueous sodium bicarbonate, with water, dried and evaporated to dryness under reduced pressure. The residue was triturated with hexane, cooled and filtered. The product was washed with hexane and dried under reduced pressure to obtain 115 g of 2-isopropylacetanilide melting at 67°-68° C. was washed with water, with aqueous sodium bicarbonate, with water dried evaporated to dryness under reduced pressure The residue was triturated with hexane cooled filtered The product was washed with hexane dried under reduced pressure
