Potassium Carbonate → 8alpha-Benzyloxycarbonylamino-6-n-propylergoline

Participants

Reaction Steps

A suspension of 17.5 g (ca. 46 mM) of 8α-benzyloxycarbonylaminoergoline obtained from step (c), 13.5 g potassium carbonate and 6 ml (62 mM) n-propyl iodide in 300 ml dimethylformamide is stirred for 18 hours at room temperature. The mixture is filtered and concentrated in a rotary evaporator. The residue is treated with methylene chloride and shaken with water. The organic phase is dried over sodium sulphate, filtered and concentrated to give the crude heading compound.
