実験手順

200 mg of 3-(12-acetylamino-9,10-didehydro-6-methyl-8α-ergolinyl)-1,1-diethylurea is dissolved in 10 ml of dioxane, combined with 2 ml of 20% diisobutyl aluminum hydride solution in toluene, and heated to 100° C. for 7 hours. The mixture is allowed to cool, then, under cooling, first water, thereafter 2N hydrochloric acid are added thereto, and the solution is rendered alkaline with dilute ammonia, after adding about 1 g of tartaric acid. The mixture is extracted by shaking with methylene chloride, the organic phase is dried and evaporated. The residue is charomatographed as disclosed in Example 7, thus producing 135 mg of 3-(9,10-didehydro-12-ethylamino-6-methyl-8α-ergolinyl)-1,1-diethylurea.
