Reaction Steps

A mixture of 3-hydroxy-1,5-dithiacyclooctane (5.00 grams, 30 millimoles), 2-isocyanatoethyl methacrylate (4.72 grams, 30 millimoles), tetrahydrofuran (15 milliliters), and one drop of dibutyltin dilaurate were stirred at 55° C. for three hours. The solvent was then removed under reduced pressure and the crude product was purified by column chromatography over silica gel using a mixture of ethyl acetate/hexane (30/70). The product was isolated as a white solid (7.72 grams, 79% yield). Purity and structure verification of Example 9 were confirmed by 1H NMR.
