ABSTRACT:
This invention relates to a process for producing a thiolsulfonic acid derivative of the general formula: ##STR1## wherein each of R.sub.1 and R.sub.2 is independently a lower alkyl group or a 5- or 6-membered cycloalkyl group, or alternatively R.sub.1 and R.sub.2 together with the adjacent nitrogen atom form a 5- or 6-membered heterocyclic group which may further contain an oxygen, sulfur or nitrogen atom; and R.sub.3 is (1) an aryl group which may optionally be substituted by a lower alkyl group, a halogen, a lower alkoxy group or a lower alkylthio group, (2) a lower alkyl group which may optionally be substituted by a lower alkoxy group, (3) an aralkyl group or (4) a cycloalkyl group, or a salt thereof, which comprises reacting a compound of the general formula: ##STR2## wherein R.sub.1 and R.sub.2 are as defined above, or a salt thereof with a compound of the general formula:
