PROCESS FOR THE PREPARATION OF 3-AMINO-4-METHOXY ACETEANILIDE

摘要

A method for preparing 3-amino-4-methoxy acetanilide of formula (I) comprises a hydrogenating-reaction of 3-nitro-4- methoxy acetanilide of formula (II) in a mixt. solvent of methanol and HAC under the condition of 20-100 atm. of hydrogen pressure Pref. the weight ratio of methanol to (II) is 2-20; the molar ratio of HAc to (II) is 0.2-5; the weight ratio of Raney-nickel to (II) is 0.1-5. wt.%. (I) may be used as an intermediate in the prodn. of dispersing dyes.
