Versuchsvorschrift

To a mixture of 1-(2,4-dichloro-3-hydroxymethylphenyl)-2-[4-(methylcarbamoyl)cinnamoylaminomethyl]pyrrole (148 mg), triethylamine (0.11 ml) and anhydrous dimethylformamide (1 ml) was added a 1M solution of methanesulfonyl chloride in dimethylformamide (0.77 ml) under ice-water cooling. The mixture was stirred at ambient temperature for 4 hours and partitioned between chloroform and saturated aqueous solution of sodium hydrogen carbonate. The organic layer was isolated, dried over magnesium sulfate and evaporated in vacuo to give a brown oil. The residue was purified by preparative thin layer chromatography (chloroform-methanol) to give 1-(2,4-dichloro-3-chloromethylphenyl)-2-[4-(methylcarbamoyl)cinnamoylaminomethyl]pyrrole (120 mg) as an amorphous powder.
