This novel approach provides an efficient method for preparation of N-(ergoline- 8&bgr;-carbonyl)ureas of the formula [I] which can be useful as anty-Parkisons drugs and prolactin inhibitors. One of the most potent antiprolactinic agent of the class of compounds prepared according to the present invention is Cabergoline. Silylated ergolines, which are obtained as intermediates in the process of the present invention, are novel compounds and represent a further aspect of the invention.
