Reaction Steps
Ergocryptinine (2.30 g; 4 mmoles) was dissolved in absolute ethanol (20 ml), containing methanesulfonic acid (0.3 ml; 4.62 mmoles). The clear solution was poured into absolute diethylether (300 ml) while stirring. The precipitated salt was filtered off and dried in vacuo. Ergocryptinine methanesulfonate (2.5 g; 97.6% of the theory) with a melting point of 174°-175° C. was obtained.
