合成路线1
该中间体在本合成路线中的序号:(VI)The synthesis of [14C]-cabergoline has also been described: The reaction of 6-allylergoline-8beta-carboxylic acid methyl ester (I) with hydrazine in refluxing methanol gives the hydrazide (II), which by reaction with NaNO2-HCl in water is converted to the amine (III). The reaction of (III) again with NaNO2-HCl in water, followed by reaction with SnCl2, affords the chloro derivative (IV), which is condensed with [14C]-CNK in refluxing ethanol-water yielding the nitrile (V). Hydrolysis of (V) with NaOH in refluxing ethanol affords the acid (VI), which is finally condensed with N-ethyl-N'-[3-(dimethylamino)propyl]carbodiimide in DMF.
