The reaction of methyl dihydro-lysergate (I) with cyanogen bromide in methylene chloride gives 6-cyano-8beta-methoxycarbonylergoline (II), which is treated with Zn dust and acetic acid - water to afford 8beta-methoxycarbonylergoline (III). The alkylation of (III) with propyl bromide (A) and potassium carbonate in DMF yields 6-n-propyl-8beta-methoxycarbonylergoline (IV), which is reduced with NaBH4 in dioxane - methanol to 6-n-propyl-8beta-hydroxymethylergoline (V). The mesylation of (V) with mesyl chloride in pyridine gives 6-n-propyl-8beta-mesyloxymethylergoline (VI), which is finally treated with sodium methylmercaptide in dimethylacetamide and with methanesulfonic acid.
