实验过程
85 g. of 2,4-dichloro-3-nitrophenol was reduced in 900 ml. of ethanol with 9 g. of Raney nickel as a catalyst at 40° C. and 20 excess atmosphere hydrogen pressure. After the reduction, the solution was liberated of the catalyst, acidified with hydrochloric acid, and prepared in the usual manner. 62 g. of 2,4-dichloro-3-aminophenol hydrochloride (equivalent to 70.4% of theory) was obtained in the form of white crystals with a decomposition point of 177°-183° C. The mass spectrum showed 178 mols (calc. 178). Analysis yielded the following values:
