実験手順

A solution is prepared from 1 mmol of terguride in 20 ml of anhydrous dioxane, combined with about 1.5 ml of N-iodosuccinimide at room temperature and stirred for 30 minutes. The reaction mixture is then poured into a saturated bicarbonate solution, extracted with methylene chloride and the organic phase is dried with magnesium sulfate. After evaporation of the solvent, the residue is chromatographed on silica gel, thus obtaining in a 76% yield 1,1-diethyl-3-(2-iodo-6-methyl-8α-ergolinyl)urea.
