Reaction Steps
A mixture of N-[4-(4-cyclohexylphenyl)-5-methyl-2-thiazolyl]thiourea (1.00 g), 4-methoxy-2,6-dimethylphenylsulfonamide (1.30 g), potassium carbonate (500 mg) and xylene (40 ml) was refiuxed with heating for 2 hours. After ethyl acetate (200 ml) was added, the mixture was washed with 2 N-hydrochloric acid and water and dried (magnesium sulfate), after which the solvent was distilled off. The residue was subjected to silica gel chromatography and eluted with methanol-chloroform (5:95, v/v) to yield a crystal of 1-[4-(4-cyclohexylphenyl)-5-methyl-2-thiazolyl]-3-(4-methoxy-2,6-dimethylphenylsulfonyl)-2-thiourea (890 mg, yield 56%). This product was recrystallized from dichloromethane-methanol to yield a colorless prismatic crystal.
