Procedure

The title compound was prepared according to General Method 16a using 4-hydroxy-6-isopropyl-6-[2-(4-methyl-thiazol-5-yl)-ethyl]-5,6-dihydro-pyran-2-one (Example E-1; 0.22 g, 0.78 mmol), toluene-4-thiosulfonic acid S-(2-tert-butyl-4-hydroxymethyl-5-methyl-phenyl)ester (Example BB-2; 0.33 g, 0.90 mmol), potassium carbonate (1.0 g, 7.2 mmol), and DMF (4 mL). The product was chromatographed on silica gel, eluting with 10% MeOH in CH2Cl2, to give the title compound, mp 138-141° C.
