Procedure
A mixture of methyl 5-t-octylsalicylate (37.7 g, 0.143 mole), 2-(2-[2-(2-chloroethoxy)ethoxy]ethoxy)tetrahydropyran (54 g, 0.124 mole), potassium carbonate (28 g, 0.217 mole) and N,N-dimethylformamide (250 ml) was heated at 140° C., under nitrogen, for 18 hours, with stirring. The mixture was cooled, diluted with ether, and then washed liberally with saturated sodium chloride solution. The ethereal solution was dried (MgSO4) and evaporated in vacuo to give an oil, which was chromatographed on silica gel to give 46 g of methyl 2-(2-[2-(2-[2-tetrahydropyranyloxy]ethoxy)ethoxy]ethoxy)-5-octylsalicylate
