実験手順
A mixture of 168.2 g of 4-amino-2-nitroanisole, 42.8 g of calcium hydroxide and 5 g of tetraethylene glycol dimethylether in 1500 g of aqueous monoethylene glycol dimethylether is reacted in accordance with the instructions of Example 1 with 150 g of 2-chloroethyl chloroformate and, after separation of the phases, with 370.6 g of 50% strength potassium hydroxide. After working up analogously to Example 1, yellow-red crystals are obtained.
