Reaction Steps
The desired benzoxazine was prepared from the reaction of ethylene diamine (0.9 g, 15 mmole), 2-[(trimethoxysilyl)propyl]phenol (7.68 g, 30 mmole, prepared as described in Example 12A), paraformaldehyde (2.1 g, 70 mmole), and toluene (20 ml). The final product was a viscous liquid. The yield was 65% of theory.
