Abstract: Dihydrocyclopentadienylamine is prepared by reacting dicyclopentadiene with hydrocyanic acid in the presence of concentrated sulphuric acid at a temperature of from -5 DEG C. to 35 DEG C., the hydrocyanic acid being used in a molar amount of at least three times that of the dicyclopentadiene and the sulphuric acid in an excess of up to 3 moles based on the dicyclopentadiene, and saponifying the resultant N-dihydrodicyclopentadienyl formamide by a conventional method.
