ABSTRACT:
Method for the preparation of N-alkoxy-(tetra- or hexahydro)-phthalimide according to formula I ##STR1## R.sub.1 being methyl or ethyl and R.sub.2 and R.sub.3 being each independently of one another hydrogen or alkyl with 1-4 C atoms or R.sub.2 and R.sub.3 together with the carbon atom to which they are bonded forming a ring with 5 or 6 C atoms, wherein the salt of the corresponding N-hydroxy-(tetrahydro- or hexahydro)-phthalimide according to formula II: ##STR2## with R.sub.2 and R.sub.3 as defined above and M being an alkali metal, is brought into contact with R.sub.1 Cl as alkylating agent, wherein R.sub.1 has the aforementioned meaning.
The N-alkoxy-(tetra- or hexahydro)-phthalimide can afterwards be converted with the aid of hydroxylamine sulphate into the corresponding alkoxyamine after which the alkoxyamine obtained can be isolated. In this manner a simple and commercially attractive process for the preparation of O-(m)ethylhydroxylamine can be implemented.
