Versuchsvorschrift

A mixture of 6.96 g (0.0376 mole) of 2-phenylsulfonylethanamine and 6.64 g (0.041 mole) of 1,1'-carbonyldiimidazole in 400 ml of tetrahydrofuran was stirred at room temperature for 1 hr. A solution of 6.16 g (0.039 mole) of N-[2-(diethylamino)ethyl]-2-propanamine in 50 ml of tetrahydrofuran was added, and the mixture was refluxed for 13 hr. The solvent was removed in vacuo, and the residue was dissolved in a 50/50 mixture of ether and methylene chloride. The solution was extracted with water and was dried over magnesium sulfate. The solvent was removed in vacuo in give an oil. Flash chromatography on silica gel (methanol) gave 5.74 g (41.36%) of clear, colorless oil:
