Reaction Steps

To a mixture of 77 mg (0.2 mmol) of 2-[4-(3-aminophenyl)piperazino]ethyl-N-(2-ethoxyphenyl)carbamate derivative and 44.6 μl (0.32 mmol, 1.6 eq) of TEA in 5 ml of THF, 71 μl (0.3 mmol, 1.5 eq) of acetyl chloride is added. Shaking is carried out at room temperature for about 20 hours. Then H2O is added and the aqueous phase is extracted with CH2Cl2. After drying on Na2SO4 and concentration under vacuum, a white solid is obtained which is purified by column chromatography (eluent CH2Cl2/iPrOH 9:1) to produce 36 mg of the expected product as a brown oil (yield: 43%).
