Abstract

The present invention relates to a process for preparing 1-adamantyltrimethylammonium hydroxide, by A) reacting 1-adamantyldimethylamine with dimethyl sulfate to give 1-adamantyltrimethylammonium sulfate; and B) subjecting the 1-adamantyltrimethylammonium sulfate obtained in A) to anion exchange with an ion exchanger loaded with OH ions.
