4-Chloro-3-nitrobenzaldehyde is a potent inhibitor of VCAM-1 expression and a potential drug candidate for autoimmune and allergic inflammatory diseases. | [Synthesis]
General procedure for the synthesis of 4-chloro-3-nitrobenzaldehyde from 4-chlorobenzaldehyde: 4-chlorobenzaldehyde (70 g, 0.5 mol) was added in batches to a mixture of nitrosonitrous nitric acid (55 mL) and sulfuric acid (55 mL) at 5°C with continuous stirring for 2 hours. Upon completion of the reaction, the reaction mixture was slowly poured into ice water (1 L) while stirring was maintained. Subsequently, the precipitate was collected by filtration and recrystallized with ethanol/water solvent mixture to afford the target product 4-chloro-3-nitrobenzaldehyde (90 g, 97% yield) as white needle-like crystals. The melting point of the product was 62-63 °C. | [References]
