実験手順
A solution of 1.16 g of N-methyl-4-methoxy-2-nitroaniline (prepared as described in Preparation 24) in 50 ml of ethanol was shaken in an atmosphere of hydrogen and in the presence of 0.3 g of 10% w/w palladium-on-charcoal for 3 hours. At the end of this time, the palladium-on-charcoal was filtered off, and the filtrate was freed from the solvent by evaporation under reduced pressure, to give 1.17 g of the title compound having an Rf value=0.50 (on thin layer chromatography on silica gel; developing solvent: a 1:3 by volume mixture of ethyl acetate and hexane).
