Reaction Steps

4-Formylbenzoic acid (15 g, 100 mmol) was suspended in methanol (500 mL) and 4-chloroaniline (12.7 g, 100 mmol) was added. The resulting suspension was heated at reflux temperature for 30 minutes and subsequently cooled to approximately 35° C. Acetic cid glacial (50 mL) was added followed by sodium cyanoborohydride (4.96 g, 80 mmol) in portions. The mixture was stirred at room temperature for 30 minutes. The mixture was concentrated in vacuo to approximately 150 mL by rotary evaporation. Water (150 mL) was added and the resulting suspension was stirred at room temperature for 16 hours. Filtration, washing with water and drying afforded 26.8 g (100%) 4-[(4-chlorophenylamino)-methyl]benzoic acid as a solid.
