β-Amino-3-fluorobenzenepropanoic acid Use and Manufacturing

To 5.00 g (40.3 mmol) of 3-fluorobenzaldehyde were added 20 mL of ethanol, 4.19 g (40.3 mmol) of malonic acid and 4.66 g (60.4 mmol) of ammonium acetate, and the mixture was reacted while stirring under reflux (80 to 90)°C for 7 hours. After completion of the reaction, the obtained reaction mixture was stirred at 0 to 5°C for 1 hour and filtered to give 4.27 g of 3-amino-3-(3-fluorophenyl)-propionic acid (racemic mixtures) (isolation yield based on 3-fluorobenzaldehyde: 57.9percent) as white powder. Incidentally, physical properties of the 3-amino-3-(3-fluorophenyl)propionic acid (racemic mixtures) were as follows.
