実験手順

A mixture of iodomethane (0.7 mL, 11 mmoles), 5-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]methylene]-1-methyl-2-thioxo-4-imidazolidinone (2.5 g, 7 mmoles) and diisopropylethylamine (1.5 mL, 8.5 mmoles) in 25 mL of ethanol with enough tetrahydrofuran added to effect solution is stirred overnight under N2 at room temperature, then stirred into 250 mL of ice water. The precipitate is filtered off, rinsed with water, dried, and recrystallized from ethyl acetate to afford the product (1.6 g) 5-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]methylene]-1,5-dihydro-1-methyl-2-(methylthio)-4H-imidazol-4-one, mp 177°-178° C., retaining 0.25 equivalent of solvent of recrystallization.
