実験手順
A mixture comprising 0.4 g of the 2-(2-(1-naphthalenesulfonamido)ethoxy)-1-(imidazo[1,2-a]-pyridin-6-yl)-1-((4-methoxybenzylthio)(methylimino)methyl)cyclohexane, 0.5 ml of anisole, 5 ml of trifluoroacetic acid and 5 ml of dichloromethane was stirred under cooling with ice for 1.5 hours, followed by the addition of ice-water. The resulting mixture was alkalinized with sodium carbonate and extracted with chloroform. The chloroform phase was dried over anhydrous magnesium sulfate and ditilled to remove the solvent. The residue was purified by silica gel column chromatography (solvent:a 30:1 dichloromethane/methanol mixture) and crystallized from ethyl acetate/n-hexane to give 0.21 g of the title compound as a white powder (yield: 65%).
