実験手順
A mixture of 11 g. of 2-nitro-5-(2-methoxyethoxy) aniline, 220 ml. of methanol, 460 ml. of water, 40 g. sodium carbonate and 60 g. sodium hydrosulfite is refluxed for 15 minutes. The solution is concentrated, diluted with water and extracted with chloroform. Evaporation of the chloroform leaves 1,2-diamino-4-(2-methoxyethoxy) benzene as an oil, sufficiently pure for the next step.
