Procedure: A mixture of 11.74 g of (3-(trimethoxysilyl)propyl)amine (0.0654 mol) and of 9.9 g of diisopropylcarbodiimide (0.0785 mol, 20% excess) was heated for 6 h 30 min at 80° C. Analysis by GC then showed an amine conversion of greater than 97%. The final colorless mixture was evaporated to dryness at 100° C. under 2 mbar for 2 h to give 22.5 g of a colorless, low-viscosity liquid corresponding to the expected guanidine. The final colorless mixture was evaporated to dryness at 100° C. under 2 mbar for 2 h

Procedure: 3-Aminopropyltrimethoxysilane (11.05 g, 61.7 mmol) and methanol (20 ml) are stirred together for 30 minutes at room temperature. To the mixture is added 41.46 g (482 mmol) of methyl acrylate. The reaction mixture is heated overnight in a 30° C. oil bath. The reaction mixture is concentrated at reduced pressure to give 21.50 g of crude methyl 3-[(2-methoxycarbonylethyl)-(3-trimethoxysilylpropyl)amino]propionate, a yellow viscous oil. A mixture of the crude product, 1-[4-(2-hydroxyethyoxy)phenyl]-2-hydroxy-2-methylpropan-1-one (26.85 g, 119.7 mmol) and 1,2-dimethoxyethane (80 ml) is heated in an oil bath at 85° (bath temperature). Zirconium(IV) acetylacetonate (1.16 g, 2.38 mmol) is added, and the mixture is stirred at 85° C. overnight and then at room temperature for 24 hours. Solvent is evaporated, and approximately one-half of the crude product is passed through a silica gel column with 5:1 chloroform:methanol as eluent to obtain 15.74 g of the title compound, a yellow semisolid product. The reaction mixture is concentrated at reduced pressure

Procedure: 77.4 g 3-(amino)propyltrimethoxysilane, 43.7 g triethylamine and 25 mg di-tert.-butyl-p-cresol were dissolved under argon in 500 ml dichloromethane. 45.1 g methacryloyl chloride was slowly added dropwise at −5° C. within 1 h, and the whole was then stirred for 1 h at 0° C. The precipitated hydrochloride was filtered off and washed with dichloromethane. The volatile constituents were removed at 40° C. under reduced pressure using the rotary evaporator. A yellow liquid with precipitated solid (hydrochloride) remained. The precipitation of the hydrochloride was completed by adding 150 ml diethyl ether, the precipitate was filtered off and the filtrate concentrated at 40° C. using a rotary evaporator with introduction of dry air. The brownish liquid was freed of residual volatile constituents at 4×10−2 mbar, and the raw product (104.2 g) was distilled at a pressure of 6×10−4 mbar.
