EXAMPLE 3 6-Cyano-2,2-dimethyl-3,4-dihydro-trans-4-(2-oxo-3-thiazolidin-1-yl)-2H-benzo[b]-pyran-3-ol (E3) STR10 To a mixture of 6-cyano-3,4-dihydro-2,2-dimethyl-3,4-epoxy-2H-benzo[b]pyran (0.59 g) and 2-oxothiazolidine (0.38 g) stirred in dry dimethyl sulphoxide (30 ml) was added sodium hydride (0.11 g, 80% dispersion in oil). After stirring at room temperature for 6 hours, water (50 ml) was added and the aqueous phase extracted with ethyl acetate. The organic layer was washed with water and brine and dried over magnesium sulphate. Filtration and evaporation gave a gum (0.35 g) which was chromatographed (chromatotron, pentane-ethyl acetate gradient elution, 2 mm silica gel) to give a fraction (105 mg) which was recrystallized from ethyl acetate-pentane to give the title compound (32 mg) as crystals of m.p. 239-240 C. Mass spectrum M+ at m/z 286.0781 Calcd. for C15 H14 N2 O2 S 286.0776.
As the paragraph descriping shows that 2682-49-7 is playing an increasingly important role.
