该中间体在本合成路线中的序号:(III)The reaction of dihydrolysergol (I) with propyl iodide (II) in hot sulfolane gives the quaternary salt (III), which is treated with Na2S in the same solvent, yielding the propyl derivative (IV). The reaction of (IV) with mesyl chloride and pyridine affords the corresponding mesylate (V), which is finally treated with commercial Na-S-CH3 in DMF to afford the target methylsulfanyl derivative.
