Procedure

This compound was prepared according to the method described in the previous examples from ethylene diamine (6.0 g, 100 mmole), paraformaldehade (12.6 g, 420 mmole), 2-allyl-phenol (26.8 g, 200 mmole), and toluene (200 ml). The final product was obtained as a viscous liquid. The yield was 92% of theory.
