Another functionalization substance may be 2-[2-(undec-10-enyl)-4-(tetrahydro-2H-pyran-2-yloxy) phenoxy]tetrahydro-H-pyran. This molecule may be synthesized from 2-[4-(tetrahydro-2H-pyran-2-yloxy) phenoxy]tetrahydro-2H-pyran using any prior art process. The intermediate may be synthesized by first adding dihydropyran (0.83 mL, 9.1 mmol) and pyridinium p-toluenesulfonate (0.11 g, 0.45 mmol) to a solution of hydroquinone (0.25 g, 2.3 mmol) in CH2Cl2 (3 mL). This reaction mixture is then stirred for about 12 hours and diluted with 10 mL of CH2Cl2. The mixture is subsequently washed by 3×5 mL of NaHCO3 and 1×5 mL brine, dried over MgSO4, and concentrated to a white solid. Silica gel chromatography (4:1 hexane/ethyl acetate) provides the di-tetrahydropyran hydroquinone as a white solid (0.48 mg, 75%).
