To a solution of methyl 5-bromo-3,4-difluoro-2-((2-fluorophenyl)amino)benzoate in appropriate solvent is added base under nitrogen atmosphere, followed by Pd catalyst, phosphine ligand and (4-methoxyphenyl)methanethiol. The reaction is generally carried out at high temperature (80-130° C., prefer 90-110° C.) and normally complete within several hours (8-24 h, prefer 12-18 h). Methyl 3,4-difluoro-2-((2-fluorophenyl)amino)-5-((4-methoxybenzyl)thio)benzoate is obtained after conventional workup.
