PURPOSE:To obtain a compound useful as a curing for polyurethane and epoxy resin economically advantageously, by reacting an amine compound by using a specific crystalline metallic silicate as a catalyst at constant pressure. CONSTITUTION:An amine compound (e.g. ethanolamine) containing a group shown by the formula (R1-R4 are H or 1-4C alkyl) in the molecule is reacted in the presence of a crystalline metallic silicate catalyst at >=3kg/cm<2>, preferably 6-150kg/cm<2> absolute pressure at 200-550 deg.C to give a triethylenediamine. The catalyst is a crystalline metallic silicate having >=12, preferably 40-3,000 molar ratio of silica (SiO2) and the metal oxide (M2O3) of SiO2/M2O3 and the amount of the catalyst used is 0.1-100wt% based on the amine compound.
