Abstract
PURPOSE: To obtain titled compound useful as a raw material for synthesizing dye, pigment, agricultural chemicals, etc. by one process inexpensively in high yield, by hydrogenating a 1-nitronaphthalene in the presence of a specific solvent and catalyst to carry out a reduction, and simultaneously introducing an alkoxyl group to the 4-position of the compound.
CONSTITUTION: In a solvent of a lower alcohol and an acid (e.g., methyl alcohol, ethyl alcohol, etc., and, an acid to be used with the alcohol is sulfuric acid, benzene- solfonic acid, etc.), in the presence of a reductive catalyst (e.g., platinum-carbon, palladium-carbon, etc.), 1-nitronaphthalene or its lower alkyl substituted derivative at 2-position is hydrogenated at normal pressure at normal temperature for 1W24hr. The 4-position of the compound is alkoxylated selectively simultaneously with the reduction reaction to give the desired compound. The amount of the solvent used is an amount equimolar with the raw material compound or more, and the amount of the catalyst used is 1W10wt% based on the raw material compound.
