실험 절차

30.4 g of N,N-dimethyl-2-chloro-3-nitroaniline is dissolved in about 300 ml of MeOH and hydrogenated at 20° C. and 5 bars pressure of hydrogen using Raney nickel as catalyst. The solvent is evaporated down and the product is purified by chromatography (silica gel, eluant: petroleum ether/ethyl acetate (3/1)). 12.8 g of 2-chloro-3-dimethylaminoaniline is obtained as a brown oil.
