Reaction Steps

A solution of 20 g. (0.125 mole) of methyl-4-oxo-2,3,4,5-tetrahydrothiophene-3-carboxylate and 32 g. (0.135 mole) of 5-(3-methyl-2-octyl)resorcinol in 200 ml. of absolute ethanol was cooled in an ice-salt bath and saturated with anhydrous hydrogen chloride. The reaction mixture was allowed to stand at room temperature for 72 hours and the solid which formed was removed by filtration. Recrystallization from ethanol gave 16 g. (37%) m.p. 165°-166°. The structure was confirmed by the IR and nmr spectra.
