実験手順

To a -10° C. solution of 8 g (0.064 mole) of 1-[2-(4-aminophenyl)ethyl]-1H-imidazole and 10 mL triethylamine in 200 mL of methylene chloride add 5 mL of methanesulfonyl chloride dropwise. Stir the resulting solution at -10° C. for about 30 minutes then warm to ambient temperature for about 30 minutes. Wash the reaction mixture with water (2×100 mL). Extract with 10% aqueous sodium hydroxide (2×50 mL). The combined aqueous extracts are neutralized with ammonium chloride then extracted with methylene chloride (2×100 mL) and combined. Remove the solvent in vacuo to provide the title compound, which may be recrystallized from tetrahydrofuran.
