Abstract

PURPOSE: To prepare the titled compound useful as a raw material of pharmaceuticals and pesticides, etc., easily, in high yield, simply by the reaction of 4,6-di-t- butylresorcinol with an alkyl halide or aralkyl halide in an aqueous alkali solution, followed by debutylation.
CONSTITUTION: The objective compound of formula II (R is alkyl or aralkyl) is prepared by (1) reacting 4,6-di-t-butylresorcinol with a halogen compound of formula RX (X is halogen provided that X is not bonded to the tertiary carbon atom of the R group) (e.g. methyl iodide) in an alkaline aqueous solution, thereby suppressing the debutylation reaction, and (2) debutylating the resulting 2-substituted-4,6-di-t- butylresorcinol. The starting material can also be prepared easily by the tertbutylation of resorcinol, and the by-produced isobutylene can be recycled as the raw material.
USE: Raw material of dyes, pigments, photographic chemicals, etc.
