Abstract

PURPOSE: To obtain the titled compound in high purity and yield, by butylating an inexpensive available resorcinol as a starting raw material, reacting the resultant tert-butyl derivative with formaldehyde and a dialkylamine, and hydrogenating and removing the tert-butyl group from the hydrogenation product.
CONSTITUTION: Resorcinol of formulaIis butylated by contact with isobutylene gas in the presence of a catalyst to give a 4,6-di-tert-butyl-resorcinol of formula II, which is then aminomethylated with formaldehyde and a dialkylamine to afford a 4,6-di-tert-butyl-2-dialkylaminomethyl-resorcinol of formula III. The resultant compound of formula III is then hydrogenated to give 4,6-di-tert-butyl- 2-methyl-resorcinol of formula IV, which is then subjected to the removal of the tert-butyl group by the conventional dealkylating method to afford the aimed compound of formula V in high yield ≥80%.
USE: Raw materials for pigments, dyes, synthetic resis, etc.
