Versuchsvorschrift

Using the procedure described in WO 9857937 A2, to a solution of 13.56 g (122 mmole) p-fluoroaniline in DMF (100 mL) under nitrogen was added 23.5 g (141 mmol) of ethyl bromoacetate and 14.95 g (141 mmol) anhydrous sodium carbonate. The mixture was heated to 70° C. for 16 h and then cooled to room temperature. Water was added (500 mL) and the mixture stirred vigorously until a precipitate formed. The solid was filtered, washed with 100 mL water and dried to afford ethyl N-(4-fluorophenyl)glycine.
