Abstract
PURPOSE: The reaction of a specific aminobenzenesulfonic acid or its salt with phosgen affords the titled compound used as an intermediate of agricultural chemicals, drugs or dyes economically through simple operations.
CONSTITUTION: The reaction of phosgen with a compound of formulaI(R1WR3 are H, 1W4C alkyl, 1W4C alkoxy, halogen, nitro; M is H, mono-, di-, or trivalent metal, tertiary amine) or its salt gives the titled compound of formula II. The amount of phosgen is 0.55W1mol per one equivalent of the amino group in the compound of formulaIpreferably. When necessary, the reaction is carried out in a solvent such as water in the presence of a dehydrochlorinating agent such as sodium hydroxide.
