In a 1-liter three-necked flask equipped with a stirring device and a nitrogen substituting device, 25.00 g of 1,4-bis(4-(4-nitrophenylmethyl)phenylmethyl)benzene was dissolved in 400 milliliters of tetrahydrofuran, 2.5 g of a Pd-C catalyst (a 5% product, containing 55.9% of water) was added and contacted with hydrogen gas while cooled with water at a normal pressure and then stirred. By recrystallizing the concentrate from a tetrahydrofuran solvent, 21.13 g of a diamino compound according to the invention, that is, 1,4-bis(4-(4-aminophenylmethyl)phenylmethyl)benzene was obtained. Melting point was from 177.9° to 179.7° C.
