Reaction Conditions

Reaction Steps

2-(2-Chloro 4-nitro-phenyl)acetaldehyde (3.0 g, 15.03 mmol) and 4-fluorobenzylamine (1.88 g, 15.02 mmol) were added to methanol (45 mL) at RT and stirred for 15 minutes. The reaction mixture was cooled to 0° C. and acetic acid (15 mL) followed by solid NaBH4 (0.56 g, 15.0 mmol) were added. The reaction mixture was allowed to warm to RT and stirring continued for 2 hours. The volatiles were then removed under reduced pressure. Dichloromethane (60 mL) and water (60 mL) were added and the mixture was stirred for 15 minutes. The separated organic layer was washed with water (60 mL), brine (60 mL), dried (Na2SO4) and the solvents removed under reduced pressure to afford the title compound (3.1 g, 67%) which was used in the next step without further purification.
