Reaction Steps

At -20° C., 355 mg of 3-(13-amino-6-methyl-8α-ergolinyl)-1,1-diethylurea is reacted to the N-formyl compound with the mixed anhydride of acetic acid and formic acid and the N-formyl compound is reduced with borane-dimethyl sulfide (S. Krishnamurty, Tetrahedron Letters 1982: 3315). After chromatography, 260 mg of 1,1-diethyl-3-(6-methyl-13-methylamino-8α-ergolinyl)urea is obtained.
