Versuchsvorschrift

Using the same procedure described in Example 4, 30.2 g (0.2 mol) of 3-nitro-benzaldehyde, 37.4 g (0.44 mol) of piperidine and 39.2 g (0.19 mol) of 2,6-di-tert-butyl-phenol are allowed to react in xylene to give 48.4 g of the title compound as yellow crystals, melting at 157° C.
