ABSTRACT:
A process for preparing an alkyl sulfonate derivative comprises causing a nitrogen-containing heterocyclic compound represented by the following formula (1): ##STR1## wherein X represents --O--, --S--, --NR.sup.1 --, --Se--, --Te-- or --CR.sup.2 R.sup.3 --, in which each of R.sup.1, R.sup.2 and R.sup.3 independently represents a hydrogen atom or a lower alkyl group, Y represents a hydrogen atom, a mercapto group, an arylthio group, an aralkyl group, a sulfo group, a halogen atom, an alkyl group, an alkylthio group, an alkylsulfonyloxy group or an arylsulfonyloxy group and each of R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group which may be substituted with a sulfo group, an aryloxy group, an alkylthio group, a haloalkyl group, a halogen atom, a cyano group, a carboxy group or a sulfo group, otherwise R.sup.4 and R.sup.5, R.sup.6 and R.sup.6, R.sup.6 and R.sup.7 and R.sup.7 and R.sup.8 are, in at least one of these combinations, bonded each other to form an aromatic ring or a cycloalkene ring; to react in the presence of Lewis acid with an aliphatic sultone to give an alkyl sulfonate derivative corresponding to the above formula (1).
