该中间体在本合成路线中的序号:(III)

The synthesis of tritiated cabergoline by two similar routes has been described: 1) The acylation of 6-nor-dihydrolysergic acid methyl ester (I) with propargyl bromide yields the corresponding 6-propargyl derivative (II), which is hydrogenated with tritium gas over Pd/C in the presence of quinoline to give the ditritiated 6-allyl derivative (III). This compound is treated with 3-(dimethylamino)propylamine at 120 C, yielding the amide (IV), which is finally treated with ethyl isocyanate. 2) The reaction of the propargyl derivative (II) with 3-(dimethylamino)propylamine as before gives the amide (V). The reaction of (V) with ethyl isocyanate gives compound (VI), which is then hydrogenated with tritium as before.
