Diamino compound and production process for the same

A production process for a diamino compound represented by Formula (1):

• (wherein A1 represents a hydrogen atom or a linear or branched alkyl group having 1 to 12 carbon atoms, and one or optional methylene groups which are not adjacent in the group may be substituted with an oxygen atom;
• A2 represents a single bond or an alkylene group having 1 to 5 carbon atoms, and one or optional methylene groups which are not adjacent in the group may be substituted with an oxygen atom;
• and m represents an integer of 0 to 3;
• one amino group is bonded to any position in the ring), characterized by reacting a cyclohexylbenzene derivative represented by Formula (3):
• (wherein the respective marks are synonymous with those described above) with an acid halide represented by Formula (4):
• (wherein X represents any of a bromine atom and a chlorine atom;
• one nitro group is bonded to any position in the ring;
• and n represents an integer of 1 to 5) by the Frieldel-Crafts reaction to produce a cyclohexylphenylcarbonyl compound represented by Formula (5):
• (wherein the respective marks are synonymous with those described above), and reducing said compound after nitrating.
