合成路线1
该中间体在本合成路线中的序号:(III)The hydrogenation of 1-methyl-7,8-lysergic acid ethyl ester (I) with H2 over PtO2 gives 1-methyl-9,10-dihydroisolysergic acid methyl ester (II), which by reaction with hydrazine is converted into the corresponding hydrazide (III). The reaction of (III) with NaNO2-HCl yields the expected azide (IV), which is submitted to a Curtius degradation by heating and hydrolysis to afford 1,6-dimethyl-8(alpha)-aminoergoline (V). Finally, this compound is treated with N,N-dimethylsulfamoyl chloride (VI) and 2,6-lutidine in methylene chloride.
