Versuchsvorschrift

10 g of ethyl 4-aminophenylacetate was dissolved in 120 ml of benzene and to this was further added 25 ml of water. To this solution were added dropwise a solution of 8.6 g of p-toluoyl chloride dissolved in 20 ml of benzene and a solution of 2.4 g of 93% NaOH dissolved in 25 ml of water simultaneously under stirring over 15 minutes. After completion of the dropwise addition, the solution was stirred for 3 hours and allowed to stand overnight. After adding 200 ml of ethyl acetate, the oil layer was separated, washed with 1N-HCl solution and with a saturated solution of sodium chloride, and dried over anhydrous sodium sulfate. After distilling off the solvent, the residue was recrystallized from benzene-n-hexane to give 12 g of ethyl 4-(4-methylbenzoylamino)phenylacetate.
