    摘要： There is provided a process for producing an aromatic amine compound having an aralkyloxy or heteroaralkyloxy group, in which an aromatic nitro compound having an aralkyloxy or heteroaralkyloxy group is reacted with hydrogen under mild conditions in accordance with a simple procedure while preventing the removal of aralkyl or heteroaralkyl group and keeping stable the other substituents on the aryl group or heteroaryl group so that the substituent does not take part in the reaction, to selectively reduce only the nitro group. The present invention is directed to a process for producing an aromatic amine compound which comprises reacting an aromatic nitro compound represented by the general formula (1): wherein Ar represents an aryl group or heteroaryl group which may have a substituent, and Z represents a divalent aromatic group which may have a substituent, with hydrogen in the presence of a metal catalyst to obtain an aromatic amine compound represented by the general formula (2): wherein Ar and Z have the meaning as defined above.

    摘要： Disclosed is a commercially suitable method for producing a 1-substituted-5-acylimidazole compound. A 1-substituted-5-acylimidazole compound is produced with a high position selectivity by reacting an N-substituted amidine compound or a salt thereof with a ketone compound in the presence of a base.
