Versuchsvorschrift

Into 20 mL EtOH and 20 mL HOAc was dissolved 2 g (9.48 mmol) 4-nitroisophthalic acid, and the solution was subjected to hydrogenation at atmospheric conditions over 1 g of 5% Pd on carbon. After 16 h, mixture was filtered, and filtrate was evaporated. The residue crystallized from methylene chloride-hexane, giving 1.29 g (75%) crystalline desired intermediate.
