Versuchsvorschrift

To a stirred solution of ethyl 6-(2-aminoethoxy)-1-benzyl-2,3-dihydro-1H-inden-2-ylcarbamate (44.7 mg, 0.126 mmol; see example 193.8) in dry dichloromethane (2 ml) was added 4-dimethylaminopyridine (18.49 mg, 0.151 mmol) followed by 1-methyl-1H-imidazole-2-sulfonyl chloride (22.78 mg, 0.126 mmol). The reaction mixture was stirred at room temperature for 1 h. Added dichloromethane and washed twice with 1N hydrochloric acid. The collected organic layers were washed with water, sodium bicarbonate and brine, dried, filtered and evaporated to obtain ethyl 1-benzyl-6-(2-(1-methyl-1H-imidazole-2-sulfonamido)ethoxy)-2,3-dihydro-1H-inden-2-ylcarbamate as a white foam. m=60 mg (95%)
