The present invention provides a process for preparing 6-(lower)alkoxy-1-naphthoic acids, the corresponding esters and 5-halo substituted derivatives thereof. The process comprises reacting furoic acid with an alkoxyphenyl compound, followed by acid hydrolysis to form a mixture of alkoxy and hydroxy substituted naphthoic acids, subjecting said mixture to the action of an alkylating agent, and optionally further treating the alkylated product to another hydrolysis step or a halogenation step.
