Reaction Steps

15 g of 4-(2-(1,1,1,3,5,5,5-heptamethyltrisiloxan-3-yl)ethyl)-2-hydroxycyclohexyl 2-methacrylamidoacetate and 4.6 g of toluene and succinic anhydride are further charged into a round bottom flask equipped with a stirring bar, a reflux condenser, and nitrogen inlet. To this, triethylamine and hydroquinone are added as a catalyst and radical scavenger, respectively, and the reaction mixture is heated to 60-65° C. After completion, the product was vacuum striped, re-dissolved in chloroform, and washed with brine solution. The organic phase was passed over Tulsion T66-MP resin to remove traces of triethylamine and decolorized using activated charcoal. The organic layer was concentrated after removal of the charcoal to yield a pale yellow, viscous product.
