Disclosed is a method for producing pyrollidine of formula (I) by reacting 1.4-butandiol (BDO) of formula (II) with ammoniac in the presence of hydrogen and a supported, metal-containing catalyser, characterised in that, prior to its reduction with hydrogen, the catalytically active mass of the catalyser contains oxygen-containing compounds of aluminium, copper, nickel and cobalt and oxygen-containing compounds of tin in the wt.% range of 0.2 to 5.0%, calculated as SnO, and in that the reaction is performed in the liquid phase at an absolute pressure in the range of 160 to 220 bar, at a temperature in the range of 160 to 230oC, using ammoniac at a molar ratio to the used BDO of 5 to 50 and in the presence of 1.0 to 4.5 wt.% hydrogen relative to the quantity of BDO used.
