Reaction Steps

This benzoxazine was prepared from 4-dodecylphenol (26.2 g, 100 mmol), 3-aminopropyltriethoxysilane (22.1 g, 100 mmol), paraformaldehyde (6.3 g, 210 mmol), and toluene (150 mL). The method to prepare this compound was the same as that used to make the previous benzoxazines. The final product was a clear, faint yellow liquid. The yield was 92%.
