Versuchsvorschrift

24.4 g (0.2 mol) of 3-hydroxybenzaldehyde are mixed with 40 ml (about 0.4 mol) of 3-methylpiperidine and 20 ml (about 0.52 mol) of 100% formic acid with cooling and then stirred for 2 hours at 120° C. When the reaction mixture has cooled to room temperature, it is poured into water and rendered alkaline with ammonia, and the precipitated solid is filtered off and recrystallised from ethanol.
