Abstract

PURPOSE: To prepare the titled compound useful as an intermediate for pigments, pharmaceuticals, pesticides, etc., by reacting a specific phenylhydrazinesulfonic acid derivative with maleic acid (anhydride).
CONSTITUTION: (A) A phenylhydrazinesulfonic acid derivative of formula I (R is H, halogen or 1W3C lower alkyl; A is H or alkali metal; m and n are 1 or 2) and sodium hydroxide are dissolved in water, and an aqueous solution of (B) maleic acid and/or maleic anhydride is added thereto. The reaction is carried out at ≤100°, preferably at 60W80°C at pH3W8.5, preferably 4W7 to give the desired compound of formula II. The molar ratio of (B) to (A) is 0.8W1.5, preferably 1.0W1.2.
