Procedimiento

12 g (ca 30 mM) of 8α-benzyloxycarbonylamino)-6-n-propylergoline obtained from step (d) and 1.5 g palladium on charcoal (10% by weight) in 500 ml ethanol are hydrogenated at normal pressure until hydrogen uptake ceases. The mixture is filtered and concentrated. This resultant heading compound is crystallised from methanol.
