Procedure

The title compound was prepared according to the procedure of Example 2 using the mercaptan produced in Example 31 (1.5 g, 0.004 mol), 3-(2-n-propyl-3-hydroxy-4-acetylphenoxy)-1,2-epoxypropane (described in U.S. Pat. No. 4,565,882) (1.1 g, 0.004 mol) and anhydrous potassium carbonate (1.75 g) in methyl ethyl ketone (15 ml). The crude product was chromatographed on silica gel using 30% ethyl acetate/hexane as eluent to give 1.9 g (60%) of the product as an oil.
