Versuchsvorschrift

A solution of 1-(trans-4-acetimidoylaminocyclohexane-1-ylcarbonyl)-4-(6-chloronaphthalene-2-sulfonyl)piperazine hydrochloride (100 mg), 0-(1-acetoxyethoxycarbonyl)-4-nitrophenol (63 mg) and diisopropylethylamine (72 mg) in DMF (4 ml) was stirred at 50t for 15 hours. The reaction solution was concentrated, and the residue was dissolved in ethyl acetate, washed with water, sodium hydrogen carbonate aqueous solution and brine, dried and concentrated. The residue was purified with silica gel column chromatography (ethyl acetate) to give a colorless solid of the title compound (89 mg).
