Reaction Steps

50 mmoles of 5'-methylthio-3-phenyl-spiro[bicyclo[2.2.1]-heptane-2,2'-5-pyrroline] hydriodide are treated with 250 ml of aqueous ammonia at 70° C. andunder a nitrogen pressure of 80 bars for 24 hours. After stripping off the solvent, an oil which slowly solidifies is obtained. After conversion intothe addition salt of fumaric acid, colorless crystals of melting point 242° C. (from methanol/water 1:1) are obtained.
