실험 절차

644 mg (2.7 mmol) of 2-(2'-hydroxyethyl)amino-5-ethoxy-4-nitrotoluene were hydrogenated with a catalytic amount of palladium/active carbon (5% Pd) in 50 ml methanol. After filtering off the catalyst, the solvent was completely distilled away. 428 mg (76% of theoretical yield) of 4-amino-2-(2'-hydroxyethyl)amino-5-ethoxytoluene were obtained in pure form by thin layer chromatography. The obtained product crystals melted at 128° C.
