Procedure
At room temperature, 100 mg of 1,1-diethyl-3-(13-hydroxy-6-methyl-8α-ergolinyl)urea is dissolved in 1 ml of pyridine and 1 ml of acetic anhydride. After one hour, the mixture is poured on ice, extracted, after 15 minutes of stirring, with methylene-chloride, the organic phase is dried with sodium sulfate, and evaporated. The residue is crystallized from ethyl acetate.
