反応手順
Sodium dithionite (84 g, 0.48 m) in water (100 ml) was added to 2-nitro-3-methoxybenzoic acid (20 g, 0.10 m) in water (100 ml)/concentrated ammonium hydroxide solution (6 ml). After stirring 3 hours the product was filtered. Acidification of the filtrate, saturation with sodium chloride and extraction with ether provided a small second crop of product.
