How is 1-Chloro-2,4-dimethoxybenzene (CAS: 7051-13-0) typically synthesized?

1-Chloro-2,4-dimethoxybenzene (CAS: 7051-13-0) can be synthesized through a chlorination reaction of 2,4-dimethoxybenzene using chlorine gas in the presence of a Lewis acid catalyst, such as aluminum chloride. The reaction is typically carried out at low temperature to achieve high selectivity and yield. The process is carefully monitored to avoid the formation of undesired by-products.
