実験手順

The title compound was prepared according to General Method 16a using 4-hydroxy-6-isopropyl-6-[2-(4-methyl-thiazol-2-yl)-ethyl]-5,6-dihydro-pyran-2-one (Example E-6; 0.33 g, 1.2 mmol), toluene-4-thiosulfonic acid S-(2-tert-butyl-4-hydroxymethyl-5-methyl-phenyl)ester (Example BB-2, 0.51 g, 1.4 mmol), potassium carbonate (0.48 g, 3.5 mmol), and DMF (5 mL). The product was chromatographed on silica gel, eluting with 5% MeOH in CH2Cl2, to give the title compound, mp 98-100° C.
