Participants

Reaction Steps

10 g. 5-hydroxy-5-cyanomethyl-5H-dibenzo-[a,d]-cycloheptene (0.0405 mol), prepared according to A, are heated to boiling for 1 hour in 150 ml. isopropanol saturated with hydrogen chloride. Subsequently, one evaporates the reaction mixture (residue 9.0 g., m.p. 137° - 138° ) and recrystallises the product from a petroleum fraction boiling at 100° - 140°. The analytically pure crystals melt at 143° - 144°, the yield amounts to 7.2 g. (79% of theory).
