Reaction Steps

This compound was prepared according to the method used for the previous examples by combining 4-maleimidophenol (18.9 g, 100 mmol), 3-aminopropyltriethoxysilane (22.1 g, 100 mmol), paraformaldehyde (6.3 g, 210 mmol), and toluene (150 mL). The final product was a highly viscous red liquid. The yield was 37%.
