The development of a high-yield and low environmental impact synthesis able to deliver highly pure pergolide mesylate 1 is described. The process [seven chemical steps (four telescoped), three steps of isolation of intermediate, and only one drying] affords pergolide mesylate 1 in 75-81% overall yield from dihydrolysergic acid 4 with >99.8% purity.
