How is 4-Fluoro-1,2-dimethoxybenzene (CAS: 398-62-9) typically synthesized?

4-Fluoro-1,2-dimethoxybenzene can be synthesized through a two-step process. In the first step, methylation of o-dichlorobenzene yields 1,2-dimethoxybenzene. In the second step, this intermediate is fluorinated using hydrogen fluoride or triflic anhydride to introduce the fluoro group, yielding the target compound. The synthesis typically involves careful temperature control to achieve high yield and selectivity.
