실험 절차

A mixture of 3-methyl-2-[2-[[1-(5-methyl-1-trityl-1H-imidazol-4-yl)ethyl]amino]ethyl]-1-phenylsulfonylindole (970 mg) and powdered potassium hydroxide (819 mg) in dimethylsulfoxide (10 ml) were stirred at 70° C. for 1 hour. The resultant mixture was diluted with cold water and extracted twice with 30% tetrahydrofuran in ethyl acetate. The extracts were washed with brine, dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was chromatographed on silica gel (eluted with 5% MeOH in chloroform) to give 3-methyl-2-[2-[[1-(5-methyl-1-trityl-1H-imidazol-4-yl)ethyl]amino]ethyl]indole (611.3 mg) as amorphous powder.
