Reaction Steps

Ergosinine (5.48 g; 10 mmoles) was dissolved in absolute ethanol (60 ml), containing methanesulfonic acid (0.72 ml; 11 mmoles). The clear solution was poured into absolute diethylether (600 ml). The precipitated salt was filtered off and dried in vacuo. Ergosinine methanesulfonate (6.05 g; 98.7% of the theory) with a melting point of 190°-192° C. was obtained.
