A novel process for preparing a naphthalene derivative of the formula:n wherein R¹ and R² are a lower alkoxycarbonyl group or both may combine to form a group of the formula :n one of R³ and R⁴ is hydrogen atom or a lower alkoxy group and the other is a lower alkoxy group; ring A is a substituted or unsubstituted benzene ring, which is useful as a hypolipidemic agent, and a novel intermediate of the formula:n wherein R1, R2, R3, R4 and ring A are the same as defined above. |
